Creatures Of Habit

Both Birders and Barn Owls appear to be creatures of habit. This morning I set off early as I often do and followed my well known route across Stalmine Moss. I don’t have a driverless car yet but I think that maybe mine does this route so often that it could probably do it right now, without help from Google. Right on time and in the correct spot at the road junction was Mr Barn Owl, or maybe Mrs Barn Owl; the sexes aren’t easy to tell apart, especially in the half light of a cloudy morning.

I stopped at the rainwater flood on Rawcliffe Moss where yesterday’s rain had topped up the water level a little. There didn’t appear to be much doing at first with approximately 400 Starlings splashing around the shallows and a couple of Swallows flitting over the surface. A shoot on nearby land did the trick as first 2 Buzzards and then a dark Marsh Harrier appeared over the distant trees, the harrier in particular flying quite fast and south. It’s just a mile to the River Wyre and where to follow its course would take the harrier to the coast. 

Two Black-tailed Godwits flew over heading west. Then a flock of about 60 previously unnoticed Meadow Pipits took to the air and scattered in all directions before settling down again in the grassy field. In a further field and in amongst a dozen or more Wood Pigeons were 6 Stock Dove. 

I stopped briefly at Braides Farm where an annual flood has yet to materialise despite the rain of recent weeks. All that I found here were singles of Curlew, Buzzard, Grey Heron and Little Egret. 

The hundreds of Lapwings at Conder Green are now a thing of the recent past. I counted a mere handful before seeing that a couple of thousand and maybe more had panicked into the air, a grey mass of Lapwings beyond the railway bridge and directly above the distant River Lune. Only a Peregrine could perform that trick.

Compensation for the low count of Lapwings on the pool came with a good selection of other birds; 18 Redshank, 6 Greenshank, 6 Curlew, 3 Snipe, 1 Common Sandpiper, 1 Green Sandpiper, 3 Goosander, 3 Wigeon, 18 Teal, 3 Little Egret, 1 Grey Heron, 3 Pied Wagtail and a Kingfisher. The Kingfisher was yet another fly by, and although I watched it fish from the edge of a far island, this one seems not to come near the birder’s watch point. Little Grebe numbered 17, the same count as my last visit but short of the nineteen counted two weeks ago. 

Curlew

Over towards the railway bridge I noticed a gaggle of 19 very wary Greylag Geese, not a species which is at all common at Conder Green, at least not on the ground. The geese fed on the marsh for a while and then made their way into the creek when I noticed that one wore an orange neck collar inscribed with black lettering of “SDB”. 

Greylag Geese

Later, a quick look on the Internet revealed that the goose may have been captured on the Orkney Islands, some 450 miles north of here, and where between 2008 and 2012 hundreds of Greylags were marked with either an orange neck collar with three characters or a white plastic leg ring with three black characters. 

The Orkney Ringing Group - “The number of Greylag Geese in both the summer (c10,000) and winter (c70,000) are increasing on Orkney. The national Goose Science Advisory Group (GSAG) has identified the marking of Greylag Geese a priority in Scotland. Little is known about the movements of these birds after the breeding season. No catching has been undertaken during the winter months when the summer stock is joined by up to 60,000 winter migrants from Iceland. The degree of mixing of the two stocks is not known.”

Ringing Gold

I met Andy up at Oakenclough at 0630 for a long overdue ringing session, the first one of the autumn here. The morning was overcast but there was no rain in the forecast. And with a wind speed of 10mph there seemed good cause to expect a reasonable catch of birds. 

The Office

Following a somewhat steady start the appearance of flocks of Goldfinches flying in from surrounding areas gave a boost to our eventual numbers. We were far from disappointed with a total of 63 birds of 11 species and totals as follows: 40 Goldfinch, 4 Chaffinch, 6 Coal Tit, 3 Blue Tit, 1 Great Tit, 3 Goldcrest, 1 Blackcap, 1 Willow Warbler, 2 Chiffchaff, 1 Robin, 1 Treecreeper.

Goldfinches are certainly beginning to flock in some numbers in recent days. This morning we initially thought there to be 100+ birds in the area. This was a clear underestimate as two or more flocks may have been involved whereby a catch of 40 is indicative of 200 or more Goldfinches. 

At this time of year we expect that the majority of birds caught will be juveniles of the year rather than adults however even we were surprised to find that of today’s 40 Goldfinch, 39 were juveniles and just one an adult. More interesting still was that this single adult proved to from elsewhere as the ring number beginning with Z690 was not one of our own. The ring number will be forwarded to the BTO and the original ringing details notified to us in due course. 

Goldfinch

In contrast to the adult male above, most juveniles are still at the stage where they cannot be sexed with any certainty by their plumage. While the one below is as buff/brown as many of today’s birds, a wing length of 82 mm coupled with the large bill and black nasal feathers indicate a male.

The ringing kept us busy but in addition to the birds mentioned above we noted 1 Buzzard, 5 Pied Wagtail, 1 Common Sandpiper, 15 Lapwing, 3 Siskin and 45+ Swallows.

Short Saturday

On Saturday morning I was back home for 9am after being rained off. The weather forecast was spot on but left me a two hour slot for a spot of birding. 

Is this getting familiar to readers? Barn Owls aren’t ten a penny around here, honest. It’s just that my route north through Hambleton and Out Rawcliffe takes me past a Barn Owl location where once again a pair of owls were out hunting. I took a distance shot and then left the two looking for breakfast. 

Barn Owl

I was hoping to see the recent Marsh Harriers out on the flooded moss but there was no sign of them. As autumn migrants the harriers may have moved on already and found a more productive feeding location. 

I made do with 3 Buzzards and several Carrion Crows which didn’t venture far. They mainly sat along the fence lines apparently waiting for a meal to show nearby rather than taking to the air to find one. 

Carrion Crow and Buzzard

The water level of flooded area had dropped a little with fewer species than a few days ago. A number of Swallows mobbed a passing Sparrowhawk as the raptor scattered the flock of feeding Starlings. A good mix of birds followed with 180 Starling, 40 Lapwing, 1 Black-tailed Godwit, 3 Pied Wagtail, 3 Grey Heron, 40+ Swallows and 2 Snipe.

Common Snipe never stray far from their customary areas of living. They are most often found in areas such as brackish and fresh marshlands, grassy cover, rich moist soils, and edges of lakes, rivers, and swamps where they can easily hide if need be. These are areas that are commonly open and are low enough for them to become almost invisible in vegetation where they can be incredibly hard to spot.

Snipe
 
That left me an hour at Conder Green where from the west the sky quickly turned a grey shade of grey with rain in the offing.

Little Grebes continue to hide from prying eyes but I managed to locate seventeen again before they floated off to the island margins. I also found 24 Teal and 3 Wigeon. A Kingfisher sat briefly on the nearest island before it too did a disappearing trick. Wader counts were pretty good with 230+ Lapwings, 30 Redshank, 2 Greenshank, 1 Common Sandpiper and 1 Snipe. 

There a good flock of Goldfinch on the marsh whereby my count of 80+ is the best so far this autumn. As we might expect at this time of year, approximately 90% of the Goldfinch appeared to be  juveniles. Otherwise - 2 Pied Wagtail, 2 Little Egret and a handful of Linnets. 

Goldfinch

An hour or two that’s all but Barn Owls, Kingfishers and Buzzards can never be discounted can they?

More Of A Circus

Andy and I were due to go ringing this morning but then he cried off because of an emergency baby-sitting request. Grandparents come in useful sometimes, even if the old fools do vote the “wrong” way in referendums and generally don’t do as they are told. 

Not to worry, I decided to go birding instead of ringing. I was at the car putting on a jacket when I heard a Tawny Owl hooting from nearby gardens, a reminder of autumn and that today is the first day of September. 

The main times to hear Tawny Owls call is during the breeding season which runs from February/March to May, and then again in the autumn when the adults have finished their moult. In June and July the adults tend to go silent and only the young may be heard, squeaking for food throughout the night from dusk. August, September and October can be very active times vocally for adults as they set about reaffirming their territories in preparation for the next breeding season. 

Tawny Owl

As usual I drove over the moss road towards Pilling. It’s a more productive bird route than the main road although in the half light of this morning the best I managed was a Kestrel on the usual roadside post. Near Pilling village I saw a Barn Owl on a fence post so slowed the car in preparation for a possible photographic encounter. Not this time. The owl was away and across the fields before I could even lift the camera. 

I made for the flood at Out Rawcliffe where on Saturday 27th August I’d seen the Marsh Harrier and a few waders. Today was also the first day of the inland shooting season, something I remembered when from across the fields I heard the sound of gunfire but saw no people carrying shotguns. 

The parish of Out Rawcliffe is one of the largest in England. It takes more than a couple of hours to walk north to south or east to west over the mossland, so I wasn’t too worried that the guns would be on me soon; there was time to scope the flood for birdlife. 

Out Rawcliffe, Lancashire

On the water I counted the wildfowl as 150+ Mallards and 24 Teal. So many Mallards indicated the recent release of captive-bred birds and another reason for the sound of gunfire. By contrast the Teal are truly wild birds and recent arrivals from north and east. Waders today comprised just the two species, 220 Lapwing and 4 Black-tailed Godwits. 

Lapwings

There was a single Kestrel about plus 3 or 4 Buzzards, and then as a bonus 2 Marsh Harriers in the air together over the trees and the distant water. There was some interaction between the two harriers when I could see that both were “cream tops”, juvenile/female types with noticeable and extensive creamy foreheads. Local Swallows instinctively mobbed the pair of raptors but I can’t imagine the circling harriers were any real threat to the Swallows. 

Marsh Harrier and Swallows 

Soon a line of a dozen or more sportsmen appeared on the horizon, spread right to left at regular intervals over the maize field dotted with blue feeder bins that sate the released partridge and pheasant. The shooters were headed slowly towards the flood so it was time for me to head in the direction of Conder Green. 

In the wildfowl stakes I counted 19 Little Grebe, 5 Shoveler and 3 Wigeon on the pool, 4 Goosander in the main creek and 20+ Teal in all. Just 3 Little Egret today but a zero count of Grey Herons and a species that continues to disappoint in the numbers seen at expected and traditional locations. 

Waders obliged with 105 Lapwing, 24 Redshank, 3 Greenshank, 3 Snipe and 1 Common Sandpiper. A Kingfisher put in the usual fly-by appearance as did a passing Kestrel. 

Over near the railway bridge the nesting House Martins numbered 20+, a similar quantity to the Swallows hanging around the nearby farm buildings. Otherwise - 15 Linnet, 2 Pied Wagtail, 1 Reed Bunting. 

House Martin

I was saddened today to hear of the passing of a fellow blogger and ringing pal Lew/Errol Newman, a name that blog readers will know from reading the “Under Rydon Hill” link in the right hand sidebar.

Like me Lew was a regular visitor to Bardsey Island, Wales where our paths sometimes crossed. Lew almost singlehandedly built the main Heligoland trap in the central withy beds. It was a trap that worked like as dream and I had cause to thank Lew on a number of occasions when his construction presented me with bags full of birds and several ringing “ticks”. Lew will be greatly missed by friends, colleagues, family and his partner Jenny.

Green For Go

Another Bird Blog often highlights bird species that are in decline. Today I feature a bird in the ascendancy but the story is not one that lifts the spirits. It is more a tale of man’s inability to recognise and face up to an environmental problem that is not only all too apparent, but once again, mainly of man’s own making. 

I first encountered Ring-necked Parakeets Psittacula krameri in India in 1996 when Sue and I took the Shatabdi Express from Delhi to Agra in pursuit of experiencing the legendary Taj Mahal. Incomparable it was. Standing majestic on the banks of the River Yamuna, the white marble and ornamentation of the Taj Mahal was everything and more that books and TV led us to expect. Huge lumps formed in our throats as we walked the central path towards the monument and then waited in turn to rest on Diana’s Seat. A few Rupees later we had our picture taken and then later brought as if like magic to the return train for Delhi. 
 
The Taj Mahal, Agra - 1996

We explored the beautifully manicured grounds of the palace where several species of vultures and Black Kites circled overhead. Hundreds of Ring-necked Parakeets squawked from the tree tops and then squawked some more as they flew in all directions.  Ring-necked Parakeets are endemic to India and to warmer climates in Northern Africa and Southern Asia.

Even then in 1996 it was obvious to me that here in its natural environment of Garden India was a highly successful, abundant, and from its general demeanour, an aggressive species. In India, the late Salim Ali, an ornithologist known as ‘the Birdman of India’, referred to the parakeet as ‘one of the most destructive birds’ and one that was a serious agricultural pest.

Ring-necked Parakeets as cage bird pets have been easily available and quickly bought via UK pet shops and bird dealers for many years for less than £100. A “ charming, exotic bird, with its bright green feathers, long tail, red beak and black and pink ring around the neck and face”. 

Ring-necked Parakeet

By coincidence and around the time on my return to England in early 1996 the species began to accquire something of a novelty status to British bird watchers. Parakeets in the “wild” became a bird to “twitch”, even though the origins of such birds as escapees or deliberate releases were evident. Having seen the damned things in India I can well understand how having bought one in good faith, a cage bird devotee might quickly tire of the species’ extreme noise and aggressive nature.

The uniquely British but simplest way of dealing with a pet that has outlived its novelty value is to release it into the wild. At the same time this allows the owner to reflect that the animal is now free to continue its life while at the same time absolving the owner of guilt in the alternative of euthanasia of the poor creature. What a quick and painless solution to a vexing problem. 

Ring-necked Parakeet

Thus became the origins of a quickly burgeoning population of firstly feral and then increasing wild Ring-necked Parakeets, many thousands of miles from their rightful niche in natural evolution. The species is now well established in Britain, where it is the most northerly, wild breeding parrot species.

Over recent years, the British population has exploded until in 1983 the population was estimated at around 500 to 1,000, largely in South East England. By 2002 the population had increased to around 6,000. A 2010 study put the number at 30,000 with current day estimates of as many as 50,000 individuals and 8,000 breeding pairs, with colonies in Birmingham, Liverpool, Sheffield, Tyneside and Manchester.

Thankfully they are not in any great numbers in the part of Lancashire I live, where the less than ancient woodland gives fewer opportunities for the tree-hole nests they require. However, in many parts of Britain there is increasing concern that parakeets which nest in February possess the wherewithal to out-compete native, cavity-nesting species that breed later. Native tree-hole nesting species at risk include the Jackdaw, Stock Dove, Kestrel, Starling, Nuthatch, Little Owl, Green Woodpecker and even the Tawny Owl.

The growing population of Ring-necked Parakeets is also becoming a serious concern in relation to the parakeets’ impact on the foraging behaviour of small native garden feeding birds. The Ring-necked Parakeet has taken to British gardens in a big way with studies that suggest parakeets will spend half their time on bird-feeders, gorging on their favourite foods of seeds, nuts, berries and fruit. 

But bird-loving Brits may be feeding the parakeets at the expense of other species, as a recent study in Behavioral Ecology found that presence of parakeets leads to increased vigilance and decreased feeding in our native birds. Furthermore it found that these behavioural changes are much more pronounced than in the presence of a normally dominant native species such as the Great Spotted Woodpecker. 

The study concentrated on the effects in Great and Blue Tits, two common species in urban areas. Study of feeding stations suggested that the parakeets introduce a spatial shift in the tits' foraging behaviour which, if consistent, could feasibly cause reductions in the population of the common birds. If proven, this would represent the first case of such impact by non-native avian species in Britain, though a similar established case concerns the Grey Squirrel, another non-native species responsible for driving out the Red Squirrel. 

Ring-necked Parakeet

In 2010 the Ring-necked Parakeet became an official “agricultural pest” and as such, alongside Wood Pigeons, Carrion Crows and Magpies, they can be killed legally without special permission as long as damage is caused to crops. 

After the latest studies and news about their negative impact on our endemic bird population maybe it’s time we seriously considered removing for good the Ring-necked Parakeet from Wild Britain. Perhaps it's time we pressed Green for Go before it is too late?

Circus Time And A Prickly Subject

The flood at Rawcliffe Moss came good this morning with a Marsh Harrier, a species that is still something of a speciality in this part of Lancashire. 

I set off early through Hambleton and Out Rawcliffe where an early Barn Owl proved a good omen the birds to come on the moss. The light was far from perfect but the owl was the ideal subject matter. 

Barn Owl

On my last post there was a picture of the flood out on Rawcliffe Moss. The water is still there, topped up by recent downpours. 

Rawcliffe Moss

Today the majority of the birds on the flood were circa 400 gulls, split along the ratio of 5:1 Black-headed Gull and Common Gull with 20 or so Lesser Black-backed Gulls. A telescope earned its keep by locating in the distance 30 Mallards, 80+ Lapwing, 18 Black-tailed Godwit and 9 Snipe. There was single Spotted Redshank too, first located by the “tewit” call as it flew from left to right but then distinctive with its all dark wings and oval shaped whitish back and rump. 

There was a Buzzard watching on from the fence line on the right. After a while the Buzzard flew across to the distant treed with a gang of crows in hot pursuit when I noticed a second raptor. This one circled with the deeper and more distinctive “V” shaped wing formation typical of the harrier family rather than the flat profile of a Buzzard. During August we don’t see the Hen Harrier around here, just its relative the Marsh Harrier Circus aeruginosus , a spring and late summer migrant. Even at a distance the harrier seemed to have a very creamy head, a feature which might mark the bird as an adult.


Marsh Harrier

The Marsh Harrier's scientific name Circus aeruginosus emanated from the Greek "kirkos", a hawk or falcon that flies in a circle, while "aeruginosus" is Latin for "rusty coloured".

When the harrier disappeared from sight for a while I decided to drive up to Cockerham and Conder Green. 

The major highlight here was a Kingfisher but unfortunately a call and a fly by again rather than a photographic pose. Otherwise Lapwings were in good numbers but not necessarily on the enlarged pool with 200+ birds in flight both taking off and landing in the region of the canal and out of immediate sight. 

Other waders on the pool/creeks were 2 Common Sandpiper, 12 Curlew, 15 Redshank plus singles of Greenshank and Snipe. Meanwhile a survey of wildfowl gave 1 Goosander, 8 Little Grebe, 2 Wigeon, 24 Mallard and 2 Teal. 

Teal
Nothing much to report from Glasson Dock with the usual 5 Tufted Duck, 5 Cormorant and now down to 40+ Swallows around the yacht basin.

Cormorant

Back home there was a Hedgehog Erinaceus europaeus in the garden. I’m no expert but the animal appeared to be a young one, especially since it was out in broad daylight when the Hedgehog is supposed to be a nocturnal animal. There was a noticeable parasitic tick above one eye. Apparently hedgehogs are susceptible to these ticks which are generally harmless to them; larger numbers of such parasites are indicative of sickness.

That's all for now folks. Back soon with more birds and things to keep you entertained.

Catch Up Birding

On Tuesday we spent an hour or two at Hambleton Park. A picnic lunch with four of our grandchildren went down a treat by way of that time honoured British menu of sausage rolls, egg sandwiches, Golden Wonder crisps and blackening bananas. 

Birders never switch off do they? I couldn’t help but notice that as the sun warmed the sky a Buzzard flew from nearby trees and then upwards in search of thermals. Very quickly four other Buzzards arrived and joined in the midday fun. How these Buzzards find one another is remarkable but probably accounted for by their simply phenomenal eyesight, 6 to 8 times better than that of a human. After a little mewing and circling around the raptors went their separate ways across local farmland as I returned to the sausage rolls before the kids nicked the lot. 

Buzzard

Swallows were much in evidence too. After a slow start to the season, and apart from the now obligatory joined-up days of unwelcome wind and rain, the summer has been reasonably productive for Swallows. The mostly warmer and dryer weather of late has allowed something of a catch up to the Swallows’ intensive but necessary season of breeding. About twenty Swallows were feeding over the fields that adjoin the playground and then resting up on the overhead wires of the adjacent farm. 

Swallow

A change of note in the Swallows’ twittering conversations suggested something was wrong. Cue the appearance of an ever opportunist Sparrowhawk which appeared on the scene but partly hidden by a low hedgerow. As usual the Swallows had seen the Sparrowhawk first and sounded a warning before they scattered in all directions. I caught a glimpse of the Sparrowhawk’s brown head, white supercilium and fierce eye as it tried to hide along the hedgerow. It was a juvenile male of the year, proven when ten minutes later I saw it over the trees chasing Swallows but failing miserably to catch one. A young Sparrowhawk will soon learn that stealth rather than a chase will catch the next meal, especially where Swallows are concerned. 

Thursday. Free from family fortune I set off for Cockerham via the moss roads where I realised just how much rain had fallen during the last 4 days. It’s a handy looking flood which may prove to be worth a look for a week or two. I didn’t count the hundreds of gulls but focused in on the far bank where 15 Black-tailed Godwits and a single Redshank fed. A single Kestrel on roadside wires proved to be a juvenile, my first and only of the year so far. 

Rawcliffe Moss - August

Kestrel

Then up to Cockerham where Conder Pool had transformed into Conder Lake and in the process lost a more than a few birds. Lapwings and Redshanks were much reduced with 50 or less of each together with 3 Common Sandpiper, 2 Greenshank and 4 little Egret. 

Fourteen Teal, 11 Canada Goose and 6 Little Grebe provided the wildfowl with 30+ Swallows, 20+ House Sparrows, 8 Goldfinch and a couple of Pied Wagtails in the area of the farm buildings. It was the Swallows that spotted a Sparrowhawk flap/glide slowly over before a number of the Swallows broke off from their rest and chased the hawk across the road and over the pool. 

Swallow

At the layby I encountered 2 Reed Buntings in the hedgerow together with 8 Long-tailed Tits making their way along the roadside. 

Last week I’d promised myself another look at Cockersands where the field of set-aside looked very promising for birds. 

Cockersands

The sunflowers gazed into the rising sun but I looked in vain for birds while the adjacent fields wait for a cut of grass half a metre high. Best I managed was a single Meadow Pipit, 1 Chiffchaff, 2 Whitethroat, 5 Goldfinch, 8/10 Linnets overhead and plenty of Wood Pigeons. 

 Whitethroat

After those few days off it was good to catch up with a spot of birding and while the weather looks a bit mixed for the next few days, there will be more birds soon via Another Bird Blog.
