Stick Or Twist

There was a 6° and cold but clear start to the latest ringing session at Cockerham. I’d met Andy on site at 0730 and within minutes we had a few nets up. 

Linnets began to arrive but in less numbers than recent weeks. Our best Linnet count today was 130+. As the morning progressed we wondered if constant attention from two, possibly three, or even four Sparrowhawks big and small had caused the previously large Linnet flock to fragment into the smaller groups we saw. 

These Sparrowhawks must find the Linnets a relatively easy catch as they appeared a number of times and used various methods by which to catch Linnets, succeeding just once. In comparison the hawks appeared to ignore the flocks of Starlings we saw throughout the morning. 

Sparrowhawk

Less Linnets round and about meant a smaller catch of that species, balanced out by more Greenfinches, a couple of Reed Buntings and a Redwing. 

Totals caught - 23 birds of 5 species -13 Greenfinch, 6 Linnet, 2 Reed Bunting, 1 Redwing, 1 Great Tit.

Quite suddenly Lapwings are back in our area in large numbers. Many flew over the ringing site this morning heading for nearby fields. And then on the way back home and through Pilling at about 1115 there seemed to be rather a lot of Lapwings in a roadside field. I stopped for a closer look and counted 1700! 

There were piles of Starlings too and although I was more interested in the Lapwings and whether Golden Plovers were in the mix, I knew that both Starlings and Lapwings had recently arrived from similar areas of Europe and that hereabouts it's not unusual to see Starlings feeding alongside Lapwings. 

British Lapwings are mostly resident, but some migrate westwards to Ireland and others fly south to France and Spain. Any remaining winter population is increased to about 2 million by migrant Lapwings from continental Europe. 

From late summer, migrant Starlings from as far as Scandinavia, the Baltic States, the Low Countries, Germany, Poland and Russia join our resident Starlings to make enormous daytime flocks and to form huge night-time roosts.

At Gulf Lane, our usual catch site for Linnets there was a flock of 50+ in a very similar seed plot to the morning's site not too far away and where we have caught 144 Linnets so far this autumn. 

Now we are left in a quandary with a wealth of places in which to catch Linnets. Do we stick where we are or move soon to tried and trusted Gulf Lane and its 819 Linnets over recent winters?

Scoring More

After Saturday’s disappointing foray into the hills Andy and I turned our attention back to the flat fields of Cockerham on Sunday morning. There was zero wind and a cold start until the sun rose to warm the air. We employed two nets only, one in the seed plot and one in the nearby trees, a fast job of setting up that took all of 15 minutes and so much quicker to pack away. And much closer to home for the drive back- for me at least! 

There was a somewhat slow start with 4 Linnets caught in the first hour. Fortunes bucked up quickly and then a good catch of 37 birds with some superb bird watching in-between. 

For once it was Greenfinches that topped the catching chart, not Linnets. All new birds no recaptures - 19 Greenfinch, 13 Linnet, 2 Reed Bunting, 2 Wren, 1 Chaffinch.

Thanks to watchful crows we’d had early but brief views of a Peregrine, an hour or so later bettered by the sight of a Peregrine chasing a Wood Pigeon across the open field in front of us. It all happened very quickly but the pigeon proved up to the challenge by diving into the nearby copse where the Peregrine would not venture. 

Later, the morning turned out so warm, inviting and spring like that we agreed “October 10th, it’s not too late for a Marsh Harrier”. Sure enough within 30 minutes a “cream top” arrived from the east, put on a gliding/hunting display and left quite quickly to the south and in the direction of the inland mosses. 

This is the Marsh Harriers’ usual route here; today’s the latest of four autumn sightings of the species. They arrive from the north or east after a journey around or across Morecambe Bay and then fly inland on a direct southerly or south west heading. Their slow but purposeful method of flight allows them to migrate while hunting over suitable landscapes of marsh, reedbeds, and farmland where they find favoured foods like frogs, small mammals and birds, such as moorhen and coot. 

Marsh Harrier

 

It’s virtually every Linnet catching session that a Sparrowhawk or two appears looking for a meal. The hawks are drawn in by the sight and sound of 200 and more chattering Linnets, in the air or feeding in the seed plot. This morning was no different as a young male Sparrowhawk appeared as if from nowhere to single out a Linnet but once again failed to catch. 

I’m not sure what the success rate is for hunting Sparrowhawks but imagine that here at least it is quite low. Sparrowhawks that hunt by surprise tactics in suburban gardens seem to do much better than these probably inexperienced youngsters. 

Not to be outdone and just as we were ready to leave the crows found us a Buzzard that circled above to give great views in sunny sky. After a couple of circuits the Buzzard too drifted off in a southerly direction. 

Buzzard

 

All three raptors, Buzzard, Sparrowhawk and Marsh Harrier are migrants through this part of Lancashire, their numbers increasing in the autumn as young birds disperse and adults wander in search of consistent and good feeding. The Peregrine is a winter visitor to these lowland and coastal areas where concentrations of waders and wildfowl provide rich pickings for the supreme hunter.

That's all for now. Back soon with more news, views and photos.

 

A Tern For The Better

Friday morning proved too breezy for ringing so with the little sun I headed for Knott End village and the viewpoints of the jetty and promenade. From here are vistas across Morecambe Bay to the English Lakes, Barrow and on suitable days, The Isle of Man. There are many birds to be seen in most seasons except for high summer when grockles appear. 

It was just here on Monday that a lady and her dog were rescued after getting stuck in mud off the end of the slipway. I’m on safe ground in saying that because she had a dog with her, the lady was probably not a birder. 

Monday 2 August - Knott End, Lancashire - @LancsLive

The poor lady was pulled unceremoniously from the sticky mud by members of Knott End Coastguard with help from the crew of the Knott End/Fleetwood ferry. She was fortunate that a fast tide was not rushing in and that local people spotted her plight, as without their help, the seemingly innocent  walk could have ended in tragedy. 

The tides and sands of Morecambe Bay are incredibly dangerous but there is no accounting for stupid when warnings are clear and abundant.  

Knott End slipway - "Beware of sinking sand and mud. Check tides and weather"

My own walk along the river path was less eventful but dictated by the incoming tide which flooded the mud, sand and mussel beds. As the land disappeared about 450 Oystercatchers flew upstream to their roost. There was a steady flow of 55+ Sandwich Terns, their breeding season at an end with many now journeying to winter off the south and west coasts of Africa. 

Out of our own UK season of Sandwich Terns from March to September I have seen the species in the winter warmth of Lanzarote, Fuerteventura and Gambia, West Africa, but wherever it is, Sandwich Terns seem to always retain their fear of man and keep a safe distance. 

This fear is not surprising when many past recoveries of ringed Sandwich Terns are from hunting in West African countries like Ghana, Senegal, Angola, Ivory Coast , Liberia and Sierra Leone. Here the trapping of terns for food is carried out by children setting noose traps on the beach baited with dead fish. Although this practice may be less prevalent than say the 1960, 70 and 80s, it is apparently still widespread in some areas.

The best and certainly the rarest birds I saw were two other terns, Little Terns, on the beach and close to a gang of a dozen or more Sandwich Terns. Soon, the two smaller terns followed their cousins out over the incoming tide. 

Little Terns used to be much more common in Autumn in the days before the familiar story of falls in their UK population.    

Factors contributing to this low productivity include predation of chicks and eggs by, Kestrels  Foxes and the crow family. other losses from nest loss due to bad weather, food shortage, and, most significantly, disturbance by humans. Most Little Terns nest along the east and south coasts of England, adjacent to some of the most densely populated areas of Britain, although many sites are now guarded in an attempt to limit disturbance.

Little Tern

Early August is the best time to see Little Terns in Lancashire. Many years ago I counted more than 100 gathered on the shore at Cockersands on a single August morning.  Sad to say it is highly unlikely such a high number will be seen again in these parts but instead the norm becomes a count by fingers of one hand. 

There seemed few other species alongside the river and the edge of the golf course except for a handful of Greenfinches, Linnets and that rarity the House Sparrow.  A good number of Collared Doves look as though they have enjoyed a successful breeding season. There's been up to a dozen around our local gardens this last week. And of course the shore and the river provide lots of gulls.

Our summer weather is looking pretty poor to at least Monday. I’m thinking that Wednesday 11th might be my next birding and/or ringing day. Fingers crossed the experts have got it wrong again. 

A French Bonus

Saturday. The bright, sunny, and wind-free morning was perfect for a return to the Sand Martin colony at Cockerham where a motionless mist net would be hidden in the shade of the quarry face. 

Andy and I had decided to return knowing that unlike the last visit, there would be youngsters this time.  At first we caught no young, just adults coming and going on their early morning forays. 

Very soon along came “MUSEUM PARIS” with number 8998514, an adult female. The French ringed Sand Martin was a bonus, almost certainly ringed at Loire Atlantique where the River Lore meets the Atlantic Ocean, where ringers catch large numbers of migrating Sand Martins  on their journeys to and from Africa. 

Sand Martin

An hour or so later we’d caught 31 Sand Martins - 24 new ones, 6 recaptures, and Paris 8998514. Included in the 24 new Sand Martins were 11 birds of the year (juveniles) the remainder all adults. All are now on the database and with luck we should receive details of the French ringed one from the French ringing scheme soon. 

Sand Martin - juvenile

The martins kept us both fairly busy in taking them from our single 60 foot net and then processing each one by age, sex, breeding condition, wing and weight.  

Wing lengths varied with the shortest juvenile wing length of 84mm and then up to 105, the tinier wing lengths an indication of their age. During database input three of the juveniles threw up a DemOn message as potential errors on wing length measurement. The measurements were correct  and provided a clue to the fact that the young martins were very recently fledged and yet to complete their growth to adulthood.       

Meanwhile adult wings ranged from 103 to 111mm. The eleven juveniles weighed consistently heavier than the adults so it looks like the current fine weather is producing plenty of insect food. Juveniles - 12.3gms to 14.6gms adults from 11.8gms to 13.8gms. 

There was little time for birding except to note two pairs of Oystercatcher and a single but vocal Whooper Swan, the latter a left over from winter. By rights the Whooper Swan should now be several hundred miles away in Iceland. 

Whooper Swan

A pair of Little Ringed Plovers flew in briefly but left quickly when the resident pair of Oystercatchers started throwing their weight around. We think the plovers flew off in the direction of Conder Green where at least one has been present since April without any reports of breeding success.  

Little Ringed Plover

Back home in the garden there was a nest full of 5 Greenfinch chicks at an ideal age for ringing. 

It’s good to report that around here at least Greenfinches are doing better than for a number of years. The songs and calls of Greenfinches are back on the soundtrack of garden birds and I do think we have a small colony of the species in local gardens and hedgerows. 

“Trichomonosis is the name given to a disease caused by the protozoan parasite Trichomonas gallinae. It has been recorded in a number of garden bird species and is widely acknowledged to be the causal factor in the rapid decline of the British Greenfinch population first noted in late summer 2006.”

Let’s hope that Greenfinches are making a real comeback. A cause for celebration.

 

Too Few Birds

Last week saw a combination of rain, northerly winds and cold temperatures that conspired to prevent early migrants moving our way.  Internet bird news confirmed the paucity of birds - a flurry of Chiffchaffs, the occasional Wheatear, and a smattering only of pipits and wagtails. Excitement arrived in the form of a few high flying Ospreys headed for Scotland. 

Tuesday's forecast looked likely to break the deadlock with southerly winds and temperatures forecast to be in the teens. If only.  I arranged to meet with Andy at Oakenclough at 0630 but stopped briefly for the obligatory Barn Owl. 

Barn Owl

The morning was 100% cloud with gradual clearance into a sunny but still chilly morning. Birds were few and far between and a miserly catch of just 6 birds, about as bad as it gets with neither rhyme nor reason to explain our disappointment. 

Visible migration seemed nil apart from a handful of Meadow Pipits and a high-fly flock of either Redpolls or Siskins that numbered about 25. Our catch comprised 2 Lesser Redpoll, 1 Robin, 1 Wren, 1 Dunnock and 1 Blue Tit. 

By 1100 hours we'd called time on the morning.

Other birds seen - 2 Sparrowhawk, 2 Great-spotted Woodpecker, 2 Pied Wagtail, 1 Grey Wagtail, 1 Nuthatch, 1 Buzzard, 15 Oystercatcher, 4 Lapwing. 

On the drive home back home via Rawcliffe Moss I stopped to watch a Kestrel and then spotted the pair of Highland Cattle, many miles from Scotland.

Back home we have a regular Grey Squirrel looking for food and nest building Collared Doves, Woodpigeons and Greenfinches.

More news soon I hope. "Things can only get better" for Another Bird Blog.

On reading the latest news back home it appears that migration was much more obvious in coastal locations with Sand Martins, Wheatears, Siskins and Willow Warblers in evidence.  

And There’s More

Monday was the day I couldn’t make it - Summer Holidays and Grandparents Rule. Andy had been to Oakenclough and in less than ideal conditions caught another 20 or so birds with more Willow Warblers and Blackcaps. There was even an unlikely Sedge Warbler, the second one ever up here on the edge of Pennines at 700ft above sea level. 

Tuesday’s forecast promised a better morning with less cloud and higher temperatures. At 0600 the wing gauge read zero and the reservoir resembled a sheet of glass - most unusual in this often windy, wet spot chosen as a site in which to gather rainwater.

The Reservoir 

The omens were good as the very first round saw three juvenile Willow Warblers in the nearest net. We then caught steadily until the 1030 finish mandated by a dental appointment. 

Two or three themes emerged; the continuation of movement through the site of new Willow Warblers, Chiffchaffs and Chaffinches. Also, our fourth Garden Warbler of the year. By many standards just four Garden Warblers may not seem high but after a summertime absence for many years their reappearance augurs well for the species’ return here to breed in 2021. 

A good mix of species saw 27 birds caught – 7 Willow Warbler, 4 Chaffinch, 3 Great Tit, 2 Chiffchaff,2 Goldfinch, 2 Coal Tit, 2 Blue Tit, and one each of Greenfinch, Wren, Siskin, Garden Warbler and Blackcap. 

The juvenile Siskin was almost certainly a roaming and fairly local one. We are reliably informed that North of the Border in Bonnie Scotland their Siskins still swarm around garden bird feeders like clouds of green-yellow bees. Small finches like Siskins, Redpolls and Chaffinches have little reason to leave Scotland until the weather turns inclement and/or their food depletes. 

Siskin 

2020 has seen an improvement in the fortunes of Greenfinches. Many birders report seeing better numbers and we have started to catch a few here too. The one below is a juvenile female. 

Greenfinch 

Good numbers of Chaffinches around today as there has been for a week or so. It appears that Chaffinches have had a productive breeding season. 

Chaffinch 

Seven Willow Warblers today brought our total here to 32 in the month of July as the species moves through the locality. 

Willow Warbler 

One of today’s Chiffchaffs was about as small as they come. With a wing length of 56mm and a weight of 6.8 grams it was marginally bigger than a typical Goldcrest. 

 Chiffchaff 

If this weather holds we may get a crack at the Sand Martins and/or back to Oakenclough on Friday. Stay tuned to Another Bird Blog so as not to miss out.

Pied Surprise

It’s a week since my last posting. In between has seen rain, rain, then more rain, and no chance of birding, ringing or lifting a camera. Given all the foul weather I was not surprised by news from Chris at Cockerham where after two days of relentless wind and rain he found a dead Avocet youngster, one of the chicks ringed on 24th June. 

Avocet chick 

It appears that during the bad weather the adults moved the chicks from open water to a more sheltered part of the farm but at least one succumbed. Let’s hope there are no more fatalities. Fingers crossed too that the Avocets return here in 2021. 

Avocet 

On the strength of different forecasts Wednesday morning was pencilled in as a “maybe”, and Oakenclough as the venue. The previous visit of July 1st saw the first real hints of autumn migration. 

This morning I met up with Andy and Bryan at 0630 to a 15-20 mph easterly wind, far stronger than several forecasts that all suggested 6-8 mph. After each of us had driven 40 minutes or more we decided to continue in the less than ideal conditions in the hope the wind would drop. 

As the morning wore on the wind dropped slightly and allowed us a reasonable catch of 24 birds – 21 birds of the year and three adults: 5 Willow Warbler, 4 Great Tit, 3 Chiffchaff, 2 Blackcap, 2 Chaffinch, 2 Greenfinch, 2 Goldcrest, 1 Wren, 1 Dunnock, 1 Goldfinch, 1 Pied Flycatcher. 

Oakenclough springs a few surprises on most days. Our surprise today was the juvenile Pied Flycatcher. It’s a species we never catch in mist nets despite the fact that Andy rings many nestlings from boxes a quarter of a mile away. 

Pied Flycatchers are notorious for arriving unseen on their breeding sites and then leaving in autumn equally undetected. This one, AKE3941 was ringed at the nest box along with three siblings on 28 May 2020.

Strong early winds didn’t help our birding, a highlight being a passing Peregrine Falcon as it dive bombed a local Buzzard. Otherwise a few Swallows, a Great-spotted Woodpecker, Pied Wagtail and the arrival of autumnal Goldfinches around the feeders. 

Back soon. Don’t go away.
