Mixi Maxi

What a mixed up week! Two days of wind and rain, a one day window for a ringing session followed by even more rain. And then for Friday the Met Office promised another cloudy, showery, and unsummery day. They were wrong (again) of course as I sat outside in 22°C at 1430 while Julie the mobile hairdresser trimmed what’s left of my thinning hair. 


It was Tuesday when Will and I met up for the single ringing session of the week, hoping mainly for juvenile warblers. The catch of 15 proved slightly disappointing through the lack of variety that the 15 birds gave us -  6 Reed Warbler, 5 Sedge Warbler, 1 Willow Warbler and 3 Blue Tit.

Three of the Reed Warbler were recaptures, two from this year and one from 2022. Reed Warblers are perhaps on of the most site faithful bird species, whereby individual birds will return to the same patch of reedy habitat year after year after spending their winter in middle Africa. 

Our single Willow Warbler was a very welcome bright and lemony individual after a poor spring of catching this species. 

Willow Warbler

It seems that many other ringers are reporting the dearth of Willow Warblers this autumn with little in the way of theories or evidence as to the reasons of the species’ scarcity. It is perhaps related to the very dry spring of April/May followed by the sun-baked month of June, all of which resulted in an apparent lack of insects. But now the month of July has been intensely wet, following the weather pattern of recent years, four weeks good followed by four weeks of bad and masses of insects. 

Disappointment arose because of the lack of other species around - no Whitethroats, Blackcaps or Garden Warblers when we might have expected at least a single representative of each of their species. Instead, 15 Pied Wagtail, 1 Meadow Pipit, 2 Grey Heron, 2 Little Egret, 1 Buzzard, 4 Goldfinch and 15-20 Swallows.

Compensation for the slow ringing came by way of sight of a young Yellow Wagtail mixed in with the pied variety, this an early date for a now uncommon species’ autumn dispersal. 

The three species of UK wagtails, Yellow, Grey and Pied can cause intense discussion amongst less experienced bird watchers, mainly because all three of the youngsters of each are “grey”. Below is the Yellow Wagtail subject of this post, quite grey above but with a pale yellow wash to the underparts. 

Yellow Wagtail

While the Pied Wagtail is fairly easily sorted, and leaving aside for now the pitfalls of spring and autumn White Wagtails and Pied Wagtails respectively, the ID differences between Grey Wagtails and Yellow Wagtails causes discussion, not least amongst followers of Another Bird Blog. 

In August 2016 and again in July 2021 I decided to remedy this with the post “Yellow Or Grey”, a posting that has since proved to be the most read post in 15 years blogging.  Yellow or Grey

Enjoy the weekend everyone, be it grey, yellow, pied, or better still, sunny,

A Good Mix

I missed a few visits in May due to a holiday in Greece but prior to that, early April had been my last visit to Oakenclough when we caught 15 birds – 6 Lesser Redpoll, 2 Goldfinch, 2 Coal Tit, 1 Dunnock, 1 Reed Bunting, 1 Chaffinch, 1 Great Tit, 1 Siskin. 

Andy and Will filled in the gaps of May and now it was my turn to see how the breeding season was shaping, more so following the exceptionally dry and hot month of June. Would there be juveniles of the year, adults in moult or even the beginning of post-juvenile dispersal to bring new birds on the block? Time would tell. 

And talking of time, a five o’clock alarm followed by a meet with Andy at six hours past midnight seemed an ungodly hour for those of us accustomed to leisurely days on a Greek beach or breakfast in a sunny Stalmine garden. 

A slow start didn’t really pick up speed. We finished at 1100 with 20 new birds of 11 species and an interesting mix of 3 Robin, 2 Garden Warbler, 2 Siskin, 2 Goldcrest, 2 Willow Warbler, 2 Blue Tit, 2 Coal Tit, 2 Long-tailed Tit, 1 Song Thrush, 1 Chiffchaff, 1 Oystercatcher. 

The Robins caught were all fresh, rusty speckled juveniles. Even at this young age Robins display the hostility so typical of adult birds that puff out their red chests when presented with a rival. In this case it is the reflection of another Robin that the young ones see in the camera lens, or pointed aggression  directed at the person taking the photograph. 
 
Robin

Four or five Garden Warblers could be heard in song this morning. And then later in the morning we caught two female Garden Warblers, both with well developed brood patches. We caught no males or recently fledged young suggesting that we need to revisit the site soon.

Two Siskins were caught at the same time, an adult male together with a recently fledged juvenile. We released the two jointly and they flew off in the same direction. 

Siskin

Just one Willow Warbler was something of a disappointment when three or four were in song throughout the area and that by late June there should be good numbers of juveniles around. We didn’t know of a Chiffchaff on site until we caught it.

A juvenile Song Thrush was a welcome addition to the mix when we catch so few nowadays.

After his success in landing three Avocets this week, Andy was at it again in the shape of a young Oystercatcher along the bank of the close by reservoir. While one chick legged it into the distance its sibling ran the “wrong” way and ended up in Andy’s net. Wader ringing totals this year – Avocet 3, Oystercatcher 1, Lapwing 0. There’s something seriously amiss in those figures for North West England when Lapwings should be winning by country miles.

Good Saturday

Following my 0525 alarm clock and the inland drive Saturday dawned bright if a little cold at 2.5°C. No problem because the sun would soon rise to bathe us bird ringers in the morning sun of Oakenclough where I met up with Andy and Will. 

Until this point England had seen its wettest March in more than 40 years. Met Office data up to 30 March showed 111.3mm of rain fell during the month, 91% more than the average. So far April has been little better but fairly normal, less rain but quite cold, therefore not helpful to the arrival of large numbers of migrant birds from southern climes. 

And whisper it quietly so as not to be “cancelled” but the Northern hemisphere may be entering a temperature cooling phase until the 2050s with a decline up to 0.3°C. Arctic summer sea ice stopped declining about a decade ago and has shown recent growth. The Greenland surface ice sheet grew by almost 500 billion tonnes in the year to August 2022, and this was nearly equivalent to its estimated annual loss. 

Of course, climate alarmists have not caught up with these recent trends because there’s more money to be made by frightening Joe Public that the world is about to end unless they subscribe to such patent nonsense.

Back to the job in hand and Saturday’s ringing. The morning was slow with 11 birds caught. Although migrant warblers were in evidence in the shape and sounds of 3 Willow Warblers, 2 Chiffchaffs and a single Blackcap we caught none of those, instead 7 Lesser Redpoll, 2 Robin, 1 Goldfinch and 1 Long-tailed Tit. 

Three male Willow Warblers stuck to their chosen song posts all morning without venturing the very few yards to our mist nets. It was as if they were reluctant to vacate the perfect spot for even a minute or two to let an interloper grab the prime location together with a passing female. 

Willow Warbler
 
Lesser Redpolls were much in evidence with at least 20 seen and heard in small parties throughout our 4 hours stay. Unusually all of the ones caught were females. Perhaps many males have already travelled further north in their search for territory?

With eyes peeled for birds on the move a single south bound Swallow was potentially going in the wrong direction unless it changed its mind upon hitting the cold that we too felt. Otherwise, three Buzzards, but not together, a single Pied Wagtail and a passing Mistle Thrush completed a good Saturday morning.

It’s An Ill Wind

Even the most enthusiastic birder needs an occasional rest day after too many bleary eyed starts so I took a few days off. Wednesday looked ok but forecasts for the rest of the week showed strengthening winds from the east so we decided on Wednesday and a less than ideal 8-12 mph. I met up with Andy and Will at the appointed 0630 and we turned our cars to face into the breeze so as to use the ringing offices of the combined hatchbacks. 

The surface of the Grizedale reservoir rippled east to west and we suspected a slow session to be on the cards whereby net rides adjacent to the private access road are open to the elements of an easterly. 

Unlike the southern counties of England we have had our share of rain with no need for hose pipe bans or panic stations following two weeks of hot weather. Here in the West, 2022 has been the most average of summers devoid of any climate catastrophes. Current water levels in the reservoir are equal to if not slightly higher than August 2018 as seen in the video below.  And any day now the pent up rains will begin, just as they always do.

  

Our early suspicions were confirmed with a catch of just 9 birds - 3 Willow Warbler, 2 Blackcap, 1 Meadow Pipit, 1 Goldcrest and horror of horrors, two Blue Tits. 

Blackcap

There was a smidgeon of obvious and visible migration with both Swallows and House Martins on the move from north to south. About 25 Swallows fed around the trees for a short time before disappearing to the south as quickly as they arrived. Meanwhile, a gang of about 50 later arriving House Martins fed on high flying insects for around an hour before they too moved west. 

Other obvious arrivals consisted of a Marsh Harrier that flew towards the west, 12/15 Pied Wagtails and 4 Grey Wagtails. Three Buzzards and 2 Ravens were more locally based, one Buzzard especially searching for a meal above the skulking and recently released Pheasant population. 

There was excitement at Marton Mere, Blackpool on Tuesday evening when a “Hobby” was seen over two and three hours and then into Wednesday morning. On Wednesday morning it was correctly identified as a Red-footed Falcon and continued to give excellent views to all and sundry. A couple of days of easterly winds are enough to frustrate us ringers but can often produce infrequent and/or unusual goodies here on the West Coast.

The winds need to both change direction and to drop in strength for me. Here’s hoping.

Six Of The Best

The early starts aren’t too much of a problem when there’s a break with a day off to relax. Thursday became something of a lie in, sitting in the afternoon sun and then afterwards cutting the grass while recharging my solar panels in readiness for Friday’s trip to Oakenclough. 

Friday’s mist over inland mosses signified a fine day ahead as the drying bales lay in wait of the tractor day ahead. 

Morning Bales
 
Another 0630 start saw Andy, Will and Yours Truly set up the ringing shop in the shade of the Mountain Ash trees now glowing red with early berries. The berries, a source of food for autumn birds, are not especially plentiful this year, perhaps  below average and in not enough quantity to sustain hungry Redwings and Fieldfares for more than a few days.   

Rowan berries

There is a belief that a bountiful rowan crop signifies a hard winter ahead, a belief that varies from place to place, country to country. We shall see, but for now and after a terribly cold spring, we are experiencing that rarity, an English Summer like the ones I recall of years 1976 and 2003. 

It is possible that people of more recent generations than I might be nudged into thinking that this summer is alarming, frightening, even catastrophic rather than simply a display of variation and periodic weather changes to which the Earth and solar system is subject. I digress, but suffice to say that not everyone is a follower of The New Religion and its absurd doom laden offshoots. 

The morning brought goodies in the form of visible migration of pipits and over 50 Swallows. Some of the pipits we caught, the Swallows we saw. 

We caught 18 new birds of just five species - 8 Willow Warbler, 6 Tree Pipit, 2 Wren, 1 Goldcrest and 1 Robin. 

We partly expected to see and hear “trepis” with the timing right coupled to clear overhead conditions suited to a notable diurnal migrant like the Tree Pipit. 

Many migratory bird species fly mainly during the night (nocturnal migrants), others during daytime (diurnal migrants) and still others during both night and day. 

The Tree Pipit is a splendid bird with its bright pink legs and fine-streaked yellowish breast. Dare I say it is a little more beautiful than its close cousin the Meadow Pipit? 

All six trepis were juveniles of the year whereby the species’ long-distance migration to Central and Southern Africa has begun in earnest in numbers that may signify a decent breeding season north of Lancashire.

In contrast, the Willow Warbler is mainly, perhaps almost exclusively a night migrant. The new ones we caught on Friday had probably arrived overnight and then settled in to feed up in readiness for the next leg of their journeys to Africa. Likewise, all eight Willow Warblers were seen to be juveniles of this season. 

Willow Warbler

Other birds noted – Sparrowhawk, 2 Raven, 6 Pied Wagtail. 

We packed in at 1130 and although we had not ringed too many birds it’s always exciting to see migration in action.

Too Many Questions Not Enough Answers

“Six-fifteen?” We agreed. It seemed like a good idea at the time until the alarm buzzed at five-fifteen when I went through the well-practiced routine of ablutions, clothes, breakfast and a flask of coffee for the day ahead. Minutes later I hit the road to Oakenclough and met Andy on the dot to a cloudy start and a light south-easterly. 

We heard the soft piping calls of a Bullfinch near to the first mist net and thought it highly likely we would catch a Bullfinch or two now that the species has returned to the site. Better still, a few recently fledged youngsters.

Within minutes of our arrival there was shower that lasted three or four minutes after which it remained dry until we left at 1115. It had been a while since our last visit here of 17 June Another Bird Blog when we had questioned the lack of newly fledged birds.    

Throughout the rest of June and through July we thought that with the exception of Sand Martins and probably Linnets, the breeding success of all species had been both late and/or poor. 

The next few hours might give more clues and develop a few theories. We finished with a better catch of 25 birds, 24 new and one recapture, an adult Bullfinch first ringed on 17 June. The only other adult caught was a male Goldcrest. 

The remaining 23 captures were all shown to be juvenile/first summer individuals, and thirteen of those Willow Warblers. We were seeing juveniles in larger numbers and in more species for the very first time this year, all to confirm our suspicions of a late breeding season here in the cool of North West England. 

In total - 13 Willow Warbler, 6 Blue Tit, 1 Chiffchaff, 1 Goldcrest, 1 Lesser Redpoll, 1 Blackbird, 1 Great Tit, 1 Bullfinch. 

The single juvenile Lesser Redpoll was a very young bird yet to begin any post juvenile moult or develop reddish tinges. We were sure it was part of a brood born quite close to the site.

A gentle blow of the crown feathers of the partly moulting “female” Goldcrest showed remnants of a male’s orange feathers.  A male quite quickly loses those orange centres used to attract a female at the start of the breeding season.

Goldcrest
 
The male Bullfinch remains in good breeding condition. It displayed an obvious incubation patch and a cloacal protuberance, plus that we did not catch the female suggest the pair may have a second clutch of eggs somewhere in the dense woodland. Like many species, the male Bullfinch does his share of incubating eggs, hence the need for a bare, warm belly. 

Bullfinch
 
Birding between bouts of ringing/processing produced the surprise sighting of a fly-by Kingfisher, only the second one ever seen here.  Also, 4 Pied Wagtails, a handful of Swallows, a Great-spotted Woodpecker and a couple of Chaffinches. 

As is often the case it’s the species not seen, caught or even heard caught that provoke the questions. Today it was “Where are the Blackcaps, the Whitethroats and the Garden Warblers”. Or, “Why only four or five Swallows and no Swifts?” 

And there’s always the perpetual one, “Why no Buzzards, on this fine morning for a circling raptor?” Well I think we all know the answer to that last one, especially when we noted young pheasants on the loose.

Minor Movement

Monday at Pilling proved fairly unproductive with yet another catch that barely reached double figures. There was a lack of warblers but a noticeable increase in the flocking behaviour of Linnets. It appears that Linnets have done OK, but for warblers the season has been less productive with post breeding dispersal*yet to kick-off. 

Eleven birds caught - 4 Linnet, 2 Robin, 2 Reed Warbler, 2 Blackbird, 1 Sedge Warbler. 

Adult male Linnets quickly lose their bright red colours and in a few weeks will look completely different after their post-breeding moult. 

Linnet

The two Reed Warblers were recaptures from 19 May 2022 and from August 2021; quite remarkably for mid-July of any years past it meant we had yet to catch a juvenile of the year. 

Reed Warbler
 
Post breeding dispersal. When juvenile birds from the last brood have successfully fledged they are no longer dependent upon their parents for feeding and training and it is common for both adults and juveniles to disperse. They are no longer tied down to the nest site when the rearing of young is over. Adults don’t need to defend their territory anymore and begin to wander further afield in search of food while youngsters head off to discover the big wide world away from their birth place. 

The week continued warm but windy from the north and it was Saturday before any morning looked suitable for another go so I met Will at 0615. The forecast of 5mph proved partly accurate as the wind increased to 10 and then 15 mph with full cloud cover by 10 o’clock and no sign of the overhyped "heatwave". 

We hit a morning of minor dispersal with a handful of warblers newly arrived from elsewhere and definitely not from our site. 

Ten birds caught - 2 Chiffchaff, 2 Sedge Warbler, 1 Willow Warbler, 1 Lesser Whitethroat, 1 Blackcap, 1 Goldfinch, 1 Linnet and 1 Great Tit. Once again, no new Reed Warblers in our catch report although a few adults still sing away. It could be that all the nests of June and July have failed. 

The Lesser Whitethroat was an adult in partial moult, the rest of the warblers being birds of the year.

The ever increasing breeze put paid to plans of catching Linnets when the net became visible to the ever wary finches. Throughout the morning we estimated 50/70 Linnets visiting the area but only one caught. 

Other birding entertainment was provided by a pair of juvenile Peregrines twice hunting a pack of Starlings. It was the rush of sound from the wings of tightly packed Starlings that alerted us to the pursuing raptors presence. 

Others - 1 Kestrel, 1 Raven, 4 Swallow, 2 Swift, 2 Little Egret, 1 Grey Heron.

No Page Threes

The last ten days proved very frustrating. Since returning from Greece in the early hours of 18 May, I’ve not been able to get out ringing or do any meaningful birding. 

Skiathos, Greece - May Days 

My return to a typically British summer of wind and rain meant that gardening and other chores took priority. There’s one thing to say in favour of the good old British climate - it certainly makes things grow, as testified by our green waste bin now bursting to overspill with clippings of grass, trees and hedgerow. 

At last, I’m free so on Saturday I met up with Andy at Oakenclough at 0600 and a promised sunny morning with less than 10mph wind and the customary cold northerlies. 

As I drove on site a buck Roe Deer leapt over the wire fence ahead and disappeared into woodland. I searched in the boot for hat and warm jacket in readiness for the display of 6°, unlike the 27° of recent Skiathos. 

There were Willow Warblers and Garden Warblers in song, a foretaste of that to follow as we caught with good variety, unspectacular numbers but thankfully not a single one of the customary titmice. In fact throughout the morning, a single Coal Tit was the only representative of the tribe. 

14 birds caught – 5 Willow Warber, 2 Chiffchaff and one each of Blackcap, Garden Warbler, Bullfinch, Goldcrest, Pied Wagtail, Robin and Dunnock. 

The adult male Bullfinch was a stunner.

Both the Blackcap and the Garden Warbler proved to be adult female with full brood patch, the Pied Wagtail a second year male.

Blackcap

The young Dunnock an example of how soon young birds are able to leave the nest and become at least partly self-sufficient when upon release it flew strongly into the trees from whence it came. 

Dunnock

We caught adult Willow Warblers only with no examples of recently fledged ones. The cold weather of May has slowed the species’ breeding season with the emergence of young a week or more away. 

Chiffchaff
 
Willow Warbler

Birding was quiet because migration is more or less over apart from late stragglers that often surprise. Several families of Greylag, 6 Oystercatcher, 2 Lapwing, 4 Pied Wagtail, 2 Mistle Thrush, 4 Swallows, 4 Garden Warblers, 12+ Willow Warblers.
