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.

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.

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.

Where Are The Kids?

Thursday - what a strange morning. We met at 0600 up at Oakenclough - Andy, Bryan and me - a sunny morning in mid-June when we might expect good numbers of both breeding adults and newly fledged juveniles. 

However, and against all expectations our catch of birds in four hours totalled a paltry twelve - 2 Willow Warbler, 2 Bullfinch, 2 Robin, 2 Blackcap, 1 Goldfinch, 2 Wren and 1 Dunnock. Only three of those twelve birds, the resident Robins and the single Dunnock, were juveniles of this year. 

A surprising aspect of the morning was the lack of juvenile Willow Warblers as opposed to the fifteen or so males still in full song in the planation. Spring 2022 was so cold, late and lacking in the timely arrival of both males and females that we suspect many Willow Warblers are still at the nesting/incubation stage where males sing while females attend to their nest. Alternatively there may be many nest failures but either way is bad news. 

Female Bullfinch AKN3608 was a recapture from the last visit while the male was new to us. Both were in prime breeding condition that suggested a nearby nest.

Both Blackcaps were male but we saw no females or newly fledged young.

The two juvenile Robins were offspring of resident birds rather than summer returning warbler species.

On the water and along the grassy banks we saw an unseasonal Whooper Swan, one that by rights should now be in Iceland. 

 

Whooper Swan

Quite why and how a Whooper Swan is up in the hills of Lancashire in mid-June is something of a mystery, but it could be the same one that summered in the Cockerham area 15 miles away in 2021 but then joined Greylags returning inland to breed. During the northerly winds and cold of May 2022 the Whooper probably felt quite at home. 

A single Buzzard soared around for a while before performing a display dive to distant trees. 

Buzzard

Buzzards are now scarce up here on the edge of Bowland where raptors must still take their chances against tech-savvy gamekeepers. In contrast to this certain and continued persecution there is informed talk of a very successful breeding season for both Hen Harriers (40+ young fledged) and Merlins on private land where the species are well watched and soundly protected. 

From nearby trees, mixed and conifer, we saw Siskin, Nuthatch, Great-spotted Woodpecker and a party of 15-20 Long-tailed Tit. Thankfully, and for the second time on the trot we retained a clean sheet for the timice family. By all accounts it would seem that they too have experienced a poor season due to a lack of caterpillar food in April and May. Our pet name for Oakenclough is "Coal Tit Central", but not on Thursday.

Others seen - 3 Grey Heron, 1 Grey Wagtail, 3 Pied Wagtail, 4 Swallow , Oystercatcher with one young.

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.

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.

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.

Change Of Scene

A number of weeks had gone by since the last visit to Oakenclough. A look here on the blog revealed it to be 2 July when we halted ringing until pal Andy would feel fit enough to return after his knee op of 15 July. Seven weeks later he returned to the fray and well on the way to full mobility. 

In the meantime I had pottered alone at Cockerham ringing mainly Linnets and Reed Warblers but looked forward to returning to the edge of the Bowland Hills and a change of species. 

Bryan joined us this morning at 0600 to a clear dry start and the promise of a trifling easterly in sunny skies. The £zillion Met Office computer programmes got it wrong again when the morning was way off the forecast of warm, sunny skies but instead produced zero sun, an occluded sky and a naggingly cold easterly breeze. 

By 1030 we had packed in with a mixed bag of species and a total of 18 birds in all - 3 Wren, 3 Blue Tit, 2 Bullfinch, 2 Goldcrest, 2 Coal Tit, 1 Great Tit, 1 Robin,1 Chiffchaff, 1 Willow Warbler, 1 Blackcap. 

In June and July there had been no evidence of Bullfinches here, a site where they once bred but not in recent years. Catching a moulting adult female and a juvenile together today signified that the species may have returned to breed in the height of summer, and while we cannot be certain, it’s a species to look out for next spring. Most of the time all birds present ringers with puzzles that they are unable to answer, part of the reason that ringing remains an essential tool of conservation research. 

The short, stubby beak of the Bullfinch is specially adapted for feeding on buds and they are particularly enthusiastic eaters of the buds of certain fruit trees. Due to their bud-eating habits, many thousands used to be legally trapped and killed each year in orchards mainly in south and central England. There are few if any commercial orchards in this part of Northern England.

With a single one caught the lack of Willow Warblers this year was again evident when many more should be around by late August/early September. There’s little doubt that the icy mornings during the whole of May put paid to the Willow Warblers’ ground nesting lifestyles.

Goldcrests have probably fared OK this year as they nest in the comparative warmth and shelter of conifer trees. The two caught today may represent the beginnings of a noticeable September and October migration.

 

Goldcrest

 

Blackcaps appear to be in short supply with a single adult male caught today.

Our birding was uneventful except for a noticeable movement of Swallows heading south and fairly high but not lingering as the morning “warmed” slightly. In all approximately 90 Swallows with several or more Sand or House Martins in the mix against the grey skies. 

There's more news and views soon. Stay tuned to Another Bird Blog.

Back Into Action

Saturday 12 0ctober. I gave my ringing pliers a squirt of WD40. What with the trip to Greece and then the bad weather, they’d been deprived of action since 8 September. 

This morning it was back to Oakenclough hoping to see and to catch some autumn migrants. While I was away in Greece Andy had good success here with 126 captures including 55 Meadow Pipits, 31 Goldcrests, 9 Chiffchaffs and a single but late Tree Pipit. 

He caught just three Lesser Redpoll at a time of year when the species should pile through in good numbers. At this time of year it is usual to think about the “good” species but also vital to consider any that are absent,species that appear in lesser numbers than usual, and most certainly, any that are absent.   

We met up at 0645 to zero wind and 50% cloud-cover and hoped for an interesting morning ahead. Given the time of year and following several previous days of poor weather it might be fair to expect a generous helping of birds. It wasn’t to be with a disappointing catch of 13 birds for four hours work – 3 Redwing, 3 Bullfinch, 2 Goldcrest, 2 Blue Tit and one each of Song Thrush, Reed Bunting and Chaffinch. 

We saw our first Redwings of the autumn when small groups arrived soon after dawn and throughout most of the morning – in all about 70/80 individuals. The Song Thrush caught was associated with these arrivals. We catch few Song Thrushes here and the ones that we do are 99% autumn birds.

It was good to catch three more Bullfinch, two first year females and a first year male. That’s eight this year to date. Fingers crossed that this species can re-establish itself in the now re-energised plantation.

At about 1030 a heavy shower with hailstones brought an early end to our session.

Pipits are Top, Burger Is Bad

Expectations were high this morning. Monday afternoon, evening and overnight had been clear and warm, perfect conditions for migrant birds setting out on a long journey. Or so we hoped. I met up with Andy before 0600 to a clear sky and zero wind. We were joined today by Bryan. 

After a slow start birds began to appear with a decent amount of visible migration heading south in the shape and sounds of 45+ Swallow, 8 Sand Martin, 30+ Meadow Pipit, 20 Tree Pipit, 12 Pied Wagtail, 2 Grey Wagtail, 2 Spotted Flycatcher and uncounted but small numbers of Chaffinch.  

In the main we targeted pipits, wagtails and warblers and  finished at midday with a catch of 45 birds and a mix of 13 species. 

It was pipits that topped the charts today, not the common Meadow Pipit, instead the less abundant Tree Pipit at the peak of the species’ autumn migration timetable and following an apparently successful breeding season. In contrast to Tree Pipits whose migration will be over by September, the migration of Meadow Pipits is just beginning and will last into October. 

Totals - 11 Tree Pipit, 2 Meadow Pipit, 8 Willow Warbler, 4 Chaffinch, 3 Chiffchaff, 3 Goldcrest, 3 Wren, 3 Robin, 3 Blue Tit, 2 Great Tit, 1 Blackcap, 1 Bullfinch, 1 Lesser Redpoll.

And now for news and a precautionary tale about crows that live in the city. 

Apparently, and according to a new study, researchers recently found that American Crows living in urban settings have higher blood cholesterol levels than their rural peers. The crows’ higher cholesterol levels came about after they picked up the eating habits of their human neighbours by eating discarded pizza slices and tossed-out cheeseburgers. 

American Crow

For the study, published just last week in the journal The Condor: Ornithological Applications, scientists measured the blood cholesterol levels of 140 crow nestlings living along an urban-to-rural beat in California. Researchers also supplied rural nestlings in New York with McDonald's cheeseburgers. The burgers were a huge success with the birds, and some gobbled as many as three a day. Other adult crows would bring home burgers to their nestlings or store them for later.

Like the city-bred crows tested in California, the New York nestlings developed higher cholesterol levels than their fast food-free peers. 

Though urban birds didn't live as long as their rural peers, on average, cholesterol wasn't to blame. 

"Despite all the bad press that it gets, cholesterol has benefits and serves a lot of essential functions," study author Andrea Townsend, a researcher at Hamilton College in New York, said in a news release. "It's an important part of our cell membranes and a component of some crucial hormones. We know that excessive cholesterol causes disease in humans, but we don't know what level would be excessive in a wild bird." 

Still, researchers don't recommend providing birds with fast food. "Wild birds haven't evolved to eat processed food, and it might have negative consequences that we didn't measure, or that will only show up over longer periods of time," Townsend said. "Feeding wild birds can be a great way to connect with nature, and it can be a refreshing change to think that we're doing something that helps animals out. At the same time, though, I do worry that some of the foods that humans give to wild animals, and living in an urban environment in general, might not be good for their health."

Friends, you have been warned. Stick to peanuts and bird seed and ditch the junk food. You know it makes sense.

Annual Bullfinch Day

The forecast was for a better morning of almost zero wind coupled with bouts of sunshine. Another 0600 start up at Oakenclough where Andy was already out of his car and ready to go.

A check of the DemOn database revealed we started the new month with 137 captures during July including 35 Willow Warblers and 24 Blackcaps, more than we expect and perhaps a sign of a good breeding season.

There were fewer birds this morning with a lack of Blackcaps but a continuation of the Willow Warbler theme with 22 new birds and zero recaptures. Totals - 10 Willow Warbler, 2 Coal Tit, 2 Wren, 2 Blue Tit and one each of Bullfinch, Goldcrest, Chaffinch, Blackcap, Chiffchaff and Great-spotted Woodpecker.

Today represents our likely annual Bullfinch catch. We see just one or two Bullfinch a year at this site and we are unable to say from where they originate. The species previously bred here in the late nineties and almost certainly still breeds fairly locally.

Despite the rather striking appearance of the male Bullfinch the species as a whole is rather discreet, unobtrusive and even secretive, a bird that is easily overlooked by anyone unfamiliar with its quiet song and calls.

  

Bullfinch 

As with the young Bullfinch, at this time of year young birds that recently left the nest can look rather fine in their fresh plumage. Conversely, adult birds can look rather scruffy after weeks of intensive work and activity in bringing up a family. 

Compare the images below - a juvenile Willow Warbler born sometime in June and an adult Chiffchaff with severely worn flight feathers. 

Chiffchaff - worn adult - 1st August 

Chiffchaff - adult 

Willow Warbler - juvenile/first summer 

Between fledging and its migration south in the autumn the young Willow Warbler will undertake a partial moult of body contour feathers but not flight feathers. This moult is necessary to replace feathers not structurally strong enough to withstand normal wear and tear adequately, or more importantly, the stress and dangers likely to be imposed by the rigours of migration to Africa.

An adult Willow Warbler is exceptional as a species in that it has two complete moults per year, one in the breeding area soon after breeding, the other in the African winter quarters.  This difference in moult strategies of adults and juveniles, and hence the appearance of autumn Willow Warblers, is often the cause of confusion by birdwatchers who claim they can age Willow Warblers in the field. 

The Chiffchaff must soon begin a complete moult and then replacement of all of its feathers in order to be fit enough to return to Africa before winter sets in. A Chiffchaff will take about 6-7 weeks to complete the staged replacement of its feathers.

The Great-spotted Woodpecker was also a juvenile - a noisy and demonstrative individual that drew blood with a series of hammer blows to my thumb.

Great-spotted Woodpecker 

And just the one Blackcap today, another juvenile and a few weeks too early to decide male or female.
