Autumn Arrives

Friday produced my first autumnal Kingfisher of 2024, whizzing back and forth across farmland drainage ditches, enough stimulus to inspire another visit on Sunday morning where I hoped for more pictures. At the same place, and if the wind speed stayed low as predicted, maybe catch and ring a few other species. 

Kingfisher

 

As an early season  breeding species of inland waters the Kingfisher is a surprisingly early returnee to coastal Fylde where the tiny and seemingly fragile fisherman is able to make a winter living wherever there’s a spot to watch, wait and then plunge. 

August and September can be an ideal time to look out for their arrival. Warmed by The Irish Sea our coastal waters here remain ice and snow free during most winters when just 15/20 miles away near Preston or Garstang the reverse can be true. 

Almost four hours later there was neither sight nor sound of a Kingfisher; such are the vagaries of trying to predict migration or to second guess a species like Kingfisher, its habits or whereabouts. 

At first, and for an hour or so, the wind was non-existent. A single net in the open except for the minimal background of vegetated fence posts remained unwavering and strangely still, quite unlike our frequently blown away ringing sessions. It wasn’t to last but in the meantime I caught in double figures, 9 Meadow Pipits and a single Willow Warbler.

As the wind speed increased so did the birds with a rather sudden but splendid arrival of dozens of Meadow Pipit, Linnet and wagtails, as if they had all waited for a breeze to give them lift off from the runway. Bright morning sunlight gave photo opportunities whereby the strengthening breeze mattered not. 

By now Meadow Pipits poured through with a rough count of 100+, joined in their arrival with mainly Pied Wagtails (30+), Linnets (45+) and even a couple each of Great-spotted Woodpecker and Sedge Warbler.

Back soon folks. Take care out there, it's a funny old world at the moment.

It Only Takes One

ALZ8035, the single Sedge Warbler we caught on 3 August 2024 at Cockerham had been ringed elsewhere. The morning was one of excruciating slowness with just 3 birds trapped. Fortunately ALZ8035 now reminds us that catching even low numbers of birds can produce interesting results. 

Birds are such creatures of habit that ALZ8035 was first ringed at Icklesham, Sussex on 1 August 2023, a juvenile of that year, and then recaptured by us almost exactly a year to the day and now an adult. 

Sedge Warbler - Icklesham and Cockerham

 

Sedge Warbler

Icklesham is a coastal migration hot spot where many species migrate from and to France in autumn and spring with April, May and then August/September the peak times when migratory birds cross the English Channel to winter further south. 

Sedge Warbler

The Sedge Warbler is a summer visitor to Britain and spends winters in Africa, south of the Sahara Desert, a long journey in both directions. We are pretty sure that ALZ8035 had not bred at our Cockerham ringing site but almost certainly travelled there from north Morecambe Bay or further afield. 

We did not catch this individual either before or after 3 August, nor would we expect to do so, such is the rapid onward migration of Sedge Warblers. 

There has been a considerable amount of work done on the feeding ecology of the Sedge Warbler Acrocephalus schoenobaenus as well as on the related Reed Warbler Acrocephalus scirpaceus. Bibby et al (1976) studied the feeding behaviour of Sedge Warblers in Dorset UK prior to migration. 

Available food in the places frequented by the birds consisted almost entirely of the reed aphid Hyalopterus pruni, also known as the mealy plum aphid, or plum-reed aphid which frequently occurred in hundreds per leaf or per flower.

The weight gains of birds feeding on these aphids varied greatly, both amongst individuals and between years. Many of the birds stayed for very short periods. Most left after just two days. 

Bibby & Green (1981) went on to compare the patterns of migration of Reed and Sedge Warblers, both of which migrate between Britain and Africa, to see how food supply distribution might influence migration. Most Sedge Warblers fattened in southern England or northern France, and overflew Iberia, while Reed Warblers paused and fattened in Portugal. The occurrence, duration of stay and rate of weight gain of Sedge Warblers depended on the abundance of Hyalopterus pruni whose seasonality and distribution was broadly sufficient to predict the migration pattern. 

Reed Warbler

Reed Warblers showed no similar restrictions of diet, did not respond to aphid abundance and were able to achieve a similar rate of weight gain any time in September or October in Portugal. 

Back soon folks. Take care, it's a dangerous world out there.

There's rain for a day or two but Saturday is pencilled in for being outdoors.

 

Making Hay

Our nearby fields are awash with cut grass drying out in readiness for winter storage. Summer finally arrived for now. Hay and silage are two common methods of preserving grass for livestock feed. Hay is made by cutting and drying grass while silage is made by fermenting the gather cuttings in an airtight container. 

Tractors fly across local fields as local farmers enjoy a long spell of warm sunny weather after the tortuous winter and equally wet spring that stopped their work for days at a time and caused a redrawing of plans. At last, fields of stunted maize gain height towards their 8/10 feet goal. Temperature is paramount for maize where the seed needs soil temperatures above 10°C to grow, temperatures that we rarely reached throughout a long, cold spring.

This is a quiet time for ringing but since my last post I too have been out and about in the sunshine, camera, long lens and bins at the ready. 

Ready Steady, Go!

 

Another Marsh Harrier came along, a silent dip and dive across the fields, looking for that elusive prize, a mammal scurrying through layered green. On its way it went, almost reluctantly in a south westerly direction as if drawn by some unknown force of nature.

Mid week saw the first of the returning Yellow Wagtails, a single juvenile amongst the dozens of Pied Wagtails.

And now I wait for comments about the grey wagtail, a Yellow Wagtail that is quite grey but assuredly a Western Yellow Wagtail, Motacilla flava, a scarce breeding species of the Fylde area that is so scarce it cannot decline further but simply disappear into the annals of history. But, always good to see, hear and recall that soft “seep seep”.  

Water at the feeding station attracted Starlings in their juvenile variations, a mixed coat of pinky grey softness with a layer of spotted insulation that for all the world looked as if it had been stuck on a belly as an afterthought.  For students of bird moult a Starling is one to tax a ringer’s entry of “age” on the BTO's DemOn database. Good subjects for a camera lens but thank goodness we don’t catch any of the noisy, forever squawking things.

Little Egrets begin to build in autumn numbers while Grey Herons subside into single sightings, two species which one might think can sustain their respective populations but seemingly not when the heron is now “scarce” and the egret “common”.

The feeding station is well situated to exploit the bokeh of the telephoto lens, where shades of vegetation green, brown and ochre compete with a spot of blue sky for an out of focus backdrop.

That’s me for a day or two. Thursday Friday we have Brett in to paint our kitchen diner - spend some dosh before our new Government,  “party of the workers” take it all from us. 

Politicians tell lies to win over gullible fools so as to win elections. Who Knew? 

See you soon folks.

The forecasts didn’t agree; now there’s a surprise, not. Maybe rain, maybe dry. So we decided to give it a go and I met up with Andy at 0700, far from the crack of dawn but best we could manage. 

Earlier in the week on Wednesday, Thursday and Friday I had seen small arrivals of the usual early birds, the species that breed fairly early and now more or less finished - Pied Wagtails and Meadow Pipits, plus small parties of Linnets numbering 10-20 individuals. Goldfinches at the feeders too, where many in their gingery brown plumage lacked the outnumbered colourful adults. Around the feeding station there is water that attracts the pipits and wagtails in their ever interesting autumnal plumage variations. Even hares stop by for a piece of the action.

In the week I saw the first autumnal returning Marsh Harrier, a male arriving from the east - dipping and diving, disappearing from view and then reappearing, eyes fixed on the ground in case of a slow moving target below.

He carried on flying west giving just a couple of chances for a picture before he was gone. 

The route is one that the Marsh Harriers always take. We spot them with increasing regularity from July and into November, as they meet the sea wall and the ditches, dykes and farmland of North Fylde after their journey from north and/or east of Morecambe bay. The harriers proceed mainly west , sometimes directly south before taking an inland scenic mostly farmland route south so as to avoid flying over the conurbations of Fleetwood, Poulton le Fylde or Blackpool. 

They are not looking for Big Macs, fish & chips or discarded sarnies, just fresh meat, a variety of prey including birds like Coot or Moorhen, frogs and mammals, especially rabbits. 

Eventually the harriers will meet the coast again around the River Ribble, all the while avoiding Preston City. 

Saturday morning ringing was uneventful, cool with spits & spots of rain and just 15 birds caught - 7 Goldfinch, 5 Reed Warbler, 2 Willow Warbler and 1 Sedge Warbler.

The end of an absorbing week. And, dare I say, the weather forecast for the week ahead and into August looks very promising with warm, windless days to spend outdoors.

Back soon folks. I'd rather be birding than watching the telly.
