Cool, Calm and Collected

Visits to the Sand Martin colony must coincide with zero or gentle winds from the east or south east. Anything else is a no-no when a billowing mist net becomes visible to keen eyed Sand Martins able to pick out an insect from many yards away and then unerringly catch the insect in flight. Our visits must also be in the cool of early morning and before the sun travels west and makes a mist net visible. 

Our third visit of the season and a perfect forecast made us pencil in Tuesday. I met Andy at 0615 to a temperature of 20°, pretty normal for a real British summer rather than the wet and windy ones of recent years. 

Two earlier visits on 4 June and then 30 June saw 119 Sand Martins caught-103 adults and 16 juveniles of the year. We still await details of one of the adults caught on 4 June that bore “Paris Museum” 8911708. 

Before today

 

It’s never easy to come up with a Sand Martin count when so many are in the air, a good number feeding over the nearby water and others toing and froing at the nest tunnels where poking out heads add to the counting difficulties. Our best guesstimate was 180/200 individuals throughout two hours of watching while working at ringing. 

The count was probably fairly accurate with a catch of 65 Sand Martins being a healthy proportion of those around. The 65 comprised 37 juveniles of the year, 17 new adults and 11 adult recaptures, the eleven recaptures all from 2021 or 2022. 

Today’s figures, especially of juveniles, suggest that the Sand Martins here are having a pretty good year following a couple of poor years caused by wet summers, failed broods and the birds’ early departure for Africa.

Sand Martin - juvenile/first summer

 

As an afterthought, here in the UK the two day heatwave green hysteria doom and gloom is out of control. It has become comical and ridiculous by confusing climate with patterns of meteorological conditions that have been with us for the last 15 billion years. 

In the 14th and 15th centuries ‘unnatural climatic phenomena’ were often blamed on ‘a great conspiracy of witches’. During the Little Ice Age in particular, when crops failed in many parts of Europe, there was a frenzy of witch-hunting. Some in society held witches directly responsible for the high frequency of climatic anomalies. 

This sounds all too familiar, like current attempts to pin the blame for weird weather of any sort on today’s witches - coal-mining, cows or motorists. 

Everyone needs to calm down and cool off. We’re safer from weather than we have ever been. It’s the ever increasing numbers of “experts” we should be afraid of. 

Other birds this morning comprised 1 Swallow, 4 Common Tern, 2 Grey Heron, 2 Oystercatcher, 2 Pied Wagtail 

I worked hard this morning doing real Citizen Science. Now it’s sunny and warm. I’m off to sit in the garden with an ice-cream and dream of holidays in Hot and Sunny Skiathos - nine weeks and counting.

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.

A Handful Of Martins

After the windswept week it was Friday before our second visit of the season to the small House Martin colony near the village of Dunsop Bridge, Forest of Bowland. The last visit here was 7 June 2022 when we caught 11 adult House Martins, the objective today being to catch more adults together with juveniles of the year. 

Andy picked me up at 0600 in his mobile ringing office and me met up with Will about 55 minutes later at the low office building that sits alongside the River Dunsop. 

"Click the pics for full size images."

The great majority of House Martins build their nests under the eaves of houses, (and other low buildings, as here in Bowland) but a few colonies can still be found on cliffs. The famous Malham Cove just over the hills into the White Rose county of Yorkshire and about 20 miles away from Dunsop is one such example - or it was the last time I was there several years ago. With the population decline of House Martins I suspect that the species has gone from that site, as it has from so many others. 

Malham Cove, Yorkshire

 

The House Martin is one of the most widespread birds in Europe, occurring from the Mediterranean all the way north to the Arctic. They are rare breeders in Iceland. Though almost all Europe’s House Martins go a long way south for the winter, a few remain in southern Spain and Portugal throughout the year. 

It is possible to attract new House Martin colonies by erecting boxes in suitable sites (as here), but beware House Sparrows will often take over martin nests, frequently ousting the rightful owners. 

Around 86% of House Martins nesting in Britain attempt to rear two broods. Though the same pair will usually remain together for a single breeding season, it is rare for the two to pair again the following year, even if both survive. A House Martin diet is almost exclusively flying insects, caught on the wing. House Martins typically feed at a higher altitude than Swallows, so the two species do not compete with each other. The House Martin’s furry legs of tiny feathers are thought to be an adaptation to protect the birds from the cooler air of higher altitudes. 

 

House Martin

We’d set off from the coast into Friday morning into a fine morning with zero wind. Upon arrival at the upland site we were greeted by low cloud with a cool, stiff and sometimes swirling wind around the building. Such conditions are far from ideal in which to catch keen-eyed martins but after the long drive we persevered. 

Five birds caught, 2 adult House Martins recaptured from 7 June, 2 new adult House Martins and a Pied Wagtail. Rather surprisingly we caught no juvenile House Martins of the year, although it soon became clear that adults going under the eaves were in the process of feeding youngsters still in the nest.  

House Martin

 

Pied Wagtail

We’ll leave it for a week or two then try to find an ideal weather morning when we hope to see more House Martins on the wing. 

This morning saw a selection of raptors in Kestrel, Sparrowhawk, Merlin and Buzzard. 

Into the stiff headwind a Common Buzzard soared around as normal but also “hovered", much like a Kestrel does. It’s relatively uncommon to see Common Buzzards perform this type of hover, and it rarely lasts for more than a few seconds at a time, unlike a Kestrel that can be stationary in the air for minutes at a time. The most likely time to see a Buzzard 'hovering' is when there's a headwind that they can use that makes them appear fixed or barely moving in the air.  It seems that some individuals develop more of a habit of doing it than others.

Other birds seen - 3 Pied Wagtail, 2 Willow Warbler, 2 Red Grouse, 2 Meadow Pipit.

Watch And Wait

Things have been quite quiet so I took a sabbatical from blogging but kept up with news and views, good and bad, whether birds or life in general. 

A trip to Cockerham on 22 June saw a meagre catch of just 8 birds that included the first two juvenile Linnets of Project Linnet 2022 but zero juveniles of both Sedge Warblers and Reed Warblers - yet another indication of our terribly cold spring, global cooling and the beginning of the next Ice Age.

Since then a week or two of weather watching resulted in a decision to visit the Sand Martins at Cockerham, our second go at catching. The first visit of the season took place on 4 June, a trip that  resulted in a successful catch of 42 adults, including "8911708 Museum Paris", a French ringed Sand Martin. We have yet to hear from the French Ringing Scheme and of that bird’s original capture. 

Today, Thursday and the last day of June I met up with Andy, Will and Bryan at the appointed 0630 to zero wind at the quarry face where the Sand Martins have their hard–won burrows. 

It appeared that numbers had increased since our last visit and we estimated 150-200 Sand Martins around the colony. We were kept busy and confirmed the earlier guesstimate with a catch of 80 Sand Martins, 51 new adults, 16 juveniles of the year and 13 recaptures, some from earlier this year, and others from 2021. 

A few of the juveniles were very young and probably left their burrows in the last day or two. To catch so many new adults so soon after our visit of 4 June suggests new adult arrivals, ones  that stayed to breed and swelled numbers in the period between 4 June and 30 June.

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.

Owls And Kestrels

A nest box with camera is a great way of monitoring birds so as not to disturb the family unnecessarily until the time comes to ring the youngsters. The images of 31 May and then 8 June from Jamie’s camera documented the Kestrel’s progress so well that we were able to set the date for ringing the chicks as Monday 13 June. I met Andy on site at 1000 where we borrowed Steve’s ladder to investigate. 

Kestrels - 31 May

Kestrels - 8 June

We expected to find three chicks but were happy no see four young and feisty Kestrels at an ideal stage to accept their new rings.

Kestrels - 13 June 

Ten minutes after ringing both adult Kestrels returned with animal food for the chicks. The same site has breeding Barn Owls and Kestrels together with Little Owls nearby, a variety of predators that points to a healthy population of voles, mice, rats and small birds in the adjacent and sympathetically farmed land. 

You can follow the progress of this Kestrel family on Jamie’s live nest box streams at https://www.facebook.com/NestBoxLive. There are birds from all over the world including Tree Sparrows, Swifts, Bluebirds plus owls and raptors alike. Be warned, the site is very addictive! 

Our visit was also timed to check the Barn Owl box that had not sent images for weeks. Andy climbed the ladder because he’s the youngest but not by much. He reported the camera lens buried in debris from many meals and their aftermath and advised the camera be cleaned and placed higher once the owls had finished. Of the four young Barn Owls just three were big enough to ring. 

Barn Owl Box

 

Barn Owl

 

Barn Owls lay 4-6 eggs but not all eggs hatch though 4 is the average as some may be infertile. Most bird species don’t start to incubate (sit on and warm) their eggs until the clutch is complete, so the eggs hatch at more or less the same time. 

Barn Owls begin incubation as soon as the first egg is laid and lay additional eggs over a period of around 8-21 days. After 31-32 days’ incubation, the eggs hatch every 2-3 days, usually in the order they were laid. This is known as “asynchronous” hatching. The age difference between the oldest and youngest nestlings can be as much as three weeks. This age variation serves to reduce the peak in food demand and spread it over a longer period. 

Today’s smallest chick will remain un-ringed because if we were to return to ring that one there is a real risk that its larger siblings might leave the box prematurely and thus be in danger in an outside world that they are not quite ready to enter. 

Back home three young Dunnocks (from 5 eggs) were old enough to be ringed and their details recorded on the BTO database, each with their personal ring number, the place of birth, their approximate age and the number of siblings in the family.

Another Martin

Last week was Sand Martins, this week it’s their blue and white cousins House Martins. While it’s relatively easy to catch Sand Martins that nest in waterside tunnels or quarries, House Martins that build mud nests under the eaves of buildings present a more difficult proposition. 

That is the main reason why over the years since the early 1990s our own Fylde Ringing Group has captured just 43 House Martins but more than 1326 Sand Martins. 

The latest Birds of Conservation Concern report of late 2021 reveals that more than 1 in 4 UK species, including Swifts and House Martins, are now in serious trouble. The UK has lost over half of its House Martin population (-57%) since 1969 and the species is now “Red-listed” and in need of further and immediate study. 

On Tuesday morning an hour's drive took us to Dunsop Bridge, Bowland and a building owned by the water company United Utilities where House Martins nest under the low slung eaves just 12ft off the ground. The building sits alongside the rocky and free-running River Dunsop that hosts piles of insect food and also places where the martins can collect mud to build their homes. 

 

House Martin

We didn’t expect to catch many and knew that it would be adults only until late June and beyond. We estimated 10 active nests and managed to catch 9 House Martins. We’ll return later in the month and into July, August and September to see how the breeding season progressed and gather more data when we catch youngsters of the year plus more adults. 

Thanks are due to United Utilities for allowing access to their works compound and to the chaps on site who put up with us for a few hours at their place of work. We all enjoyed the sights and sounds of good numbers of Pied Wagtails, Common Sandpipers, Grey Wagtails, Swallows, Mistle Thrushes. Most of all we enjoyed seeing House Martins at close quarters.

By the time we drove back towards the coast the Trough of Bowland road was busy with cyclists, walkers and other vehicles. There was a roadside juvenile Curlew that posed for a photo but the sun was not in the best situation. Lots of Meadow Pipits were in evidence together with Oystercatchers, a few Lapwings, but sadly very few Redshanks.

Back soon with more news, views and photos. The next ringing will be those Kestrels and a look in  the Barn Owl nest box.
