Knowing The Score

I’m sure the car was on autopilot this morning, instinctively heading east towards Out Rawcliffe and the moss lands where Will and I met up again on a fairly calm morning but with a BBC prognosis of worse to come. But as ever optimism is the key, and if we believed everything the experts said about the weather and waited each time for the perfect forecast we would hardly ever get out. Besides which our other philosophy and guiding principle is, “If you don’t go, you don’t know”.

We certainly knew today that it was going to be a quiet session with “phyllloscs” calling at first light but not much else. The Sedge Warblers that until two days ago had sung their hearts out in mimicking Goldfinch, Whitethroat and sundry others, were now silent with not a one caught. Even the Whitethroats dried up this morning. In fact, let’s not prolong the agony; we caught 12 birds only, 7 new and 5 recaptures. Although to be fair to ourselves we did put up two less nets as a safeguard against the likely increase in wind strength, then soon after incoming rain forced an early termination of our efforts.

Consolation for the lack of numbers came in the form of two birds always sought after when we captured a juvenile each of Garden Warbler and Lesser Whitethroat. Other new birds were singles of Robin and Whitethroat. 3 fresh Willow Warblers completed the “new” and 5 other Willow Warblers were recaptures. One of these, an adult male AVC159 had avoided us on our visits since 23 April the previous date of capture – unless of course it had been elsewhere throughout May, June, July and the first few days of August? But on the other hand we first ringed it as a juvenile on 11th July 2009, so we could reasonably expect it to be active around the plantation and find our nets during these summer months. Oh what mysteries these birds provide.

Here Comes That Rain Again

“Others” seen today before the rains came; 100+ Swallow, 6 Stock Dove, 2 Buzzard, Great-spotted Woodpecker and a Snipe.

Finally I must mention the positive feedback from readers of the blog a few days ago when I posted a picture of a Wren. So for those troubled souls, Wren Groupies, who have probably never had to extract one from a mist net, here is another picture of the infamous Wren.

Top O' The Morning

I opened the back door at 0430 to check the cloud cover and wind. It was a nicely calm, warm but moist morning after yesterday’s rain. As bats hawked around the sycamores I could hear not far away two hungry Tawny Owls calling for breakfast.

We’d arranged to kick start the month with a ringing session at Out Rawcliffe, and out there on the raised moss, about 7 miles further inland from where I live, as we erected mist nets to the sound of a barking deer, the wind speed was zero.

On the way up the farm track Will saw a Grey Partridge with 4 half-grown chicks, just a day or two after I bemoaned the lack of Grey Partridge this year. At the same time I’d also mentioned the recent lack of “The Ringers Nemesis” the Wren, Troglodytes troglodytes or “Wrigglearse” as it is affectionately known; we both hoped that the mention of that species wouldn’t have a similar effect as talking of partridges with the result that Wrens filled the nets.

Maybe the rain of Saturday, that poured down all afternoon and evening until 9 or 10pm didn’t help our cause of targeting night flying migrant warblers in the early hours, but the August 1st arrival of new birds was subdued. In all we caught 25 birds, 22 new and 3 recaptures, whereby all the new birds of recent days and weeks had now departed.

New birds: 5 Willow Warbler, 2 Chiffchaff, 6 Whitethroat, 4 Sedge Warbler, 3 Swallow, 1 Blue Tit, and 1 Wren. Other than a recapture in June, this is the only Wren caught in the plantation since the middle of October 2009.

Recaptures: 1 Willow Warbler, 1 Dunnock, 1 Song Thrush.

In addition to the silky Sylvias, the juvenile Whitethroats above, we also caught a couple of amazingly bright yellow Willow Warblers. But Pride of Place, Top of the Heap today must go to the Wren.

Other birds seen this morning. 3 Buzzard, 1 Great-spotted Woodpecker, 13 Swift flying west, 70+ Swallows south, 5 Stock Dove and 4 Reed Buntings with an overflying Nuthatch heading to the conifer wood and a probable second bird calling from the birch wood.

There Again

I thought I was in for a good one today when the sun shone brightly at first light and on the way up through Pilling I spotted a roadside Barn Owl. The bird didn’t hang about long; just enough for brief views and one or two photographs before it disappeared without trace, as did the sun, again.

Near Wrampool the fields some of them now cut seemed full of Lapwings and Curlew with at least 250 of the former and maybe 300+ Curlew, but who wants to count every last Curlew? Throughout the morning and as roadside traffic increases and farm workers take to the fields the shy Curlews fly out to the marsh where they can continue to feed undisturbed and safe from man.

Conder Green next and if I had a dollar instead of each day I have been in the last 30 years I would definitely be wealthy as I am wiser with all the pleasure given and the knowledge gained at this little spot. My count was normal as was the list of species, but I may have gripped one PW with my count of 5 Little Egrets; is it acceptable to still use the word “gripped” or does that reveal my age and past misdemeanours on certain isles in South West England? Anyway, 3 egrets rose from the back of the pool out of sight, flew over towards the Lune whilst two others continued feeding in the island shallows as I took a bad shot against the now grey sky.

Little Egrets

My Lapwing count was 130 + as birds came and went out to the estuary whilst some stayed around the pool and creeks, with 3 Common Sandpipers, 24 Redshank and several Curlews. The shy Curlew again, but I got some half decent pictures today of that wild, unwilling, photographic subject with the fantastically specialised bill; and when was the last time anyone actually looked at a Curlew?

Parked up near the hedgerow I watched Goldfinch coming and going to the thistle heads, feeding silently, but when they spooked up to the hedge I was surprised to count 25 of them, so quiet and discreetly were they buried in the thistles. From near the roadside waste bin a Stoat made as if to cross the road towards the creek, looking left and right, but when it saw my car thought better of it and retreated back into the vegetation.There aren't many wildfowl on the pool at the moment but I logged 3 Wigeon plus the ever present lonely Little Grebe.

Goldfinch

There was no sign of the Ruff this morning, or the Spotted Redshank but I dare say I will be at CG again soon. And what is a trip north without at least a cursory glance at Lane Ends?

Below the car park the resident Reed Warblers vocalised and two of them showed briefly at the reed edge, with a bit further along the fence line a party of 7 or 8 Long-tailed Tits. With rain clouds threatening and increasing wind it just about kept fine enough for a foray to Pilling Water where I counted 3 Common Sandpipers again, 2 Little Egret and 2 Grey Herons, 2 Kestrel and 4 Pied Wagtails but by now it wasn’t the best ever morning so I promised myself another visit up this way soon and returned home for Brownie points.

With luck the wind should ease overnight and allow a ringing session for Sunday.

A Little Lunch

Little Owl

I looked up “cannibal” on the Internet after Will sent me some photographs.

“A cannibal is an animal that feeds on others of its own species but it is not an unnatural characteristic: more than 140 different species have been found to show cannibalistic tendencies under various conditions.

Sexual cannibalism has been shown in for example the female Red-back Spider, Black Widow Spider, Praying Mantis, and in scorpion species where the female eats the male after mating. The more common form of cannibalism is size structured cannibalism, in which large individuals consume smaller ones. Such size structured cannibalism has been observed in the wild for a variety of taxa, including octopus, bats, toads, fish, monitor lizards, salamanders, crocodiles, spiders, crustaceans, mammals, and a vast number of insects, such as dragonflies, diving beetles, back swimmers, water striders, flour beetles, caddis flies, birds and many more.

Cannibalism is most common among lower vertebrates and invertebrates often due to a predatory animal mistaking one of its own kinds for prey. But it also occurs among mammals and birds, mainly raptors and owls, especially when food is scarce”.

In birds of prey that use a larder or provisioning system of feeding young whereby there should be no food shortage, cannibalism has still been observed. There are several ideas as to why young owls or raptors eat their smaller siblings, or even where a parent eats part or the whole of a brood, but the theories are several and the explanations very detailed, too detailed to trouble most of us.

Will emailed me these photos he took while exploring a Little Owl nest to ring the young owlets. Because the nest cavity was deep and dark he couldn’t see into the hole, but found the young by touch, and also put his camera into the cavity and took a few pictures as a means of finding out where the birds hid.

The first picture below shows the remains of a Little Owl chick that was in the process of being eaten by a second chick. The second picture shows a third chick crouching in the corner of the hollow away from the incoming camera whilst the remains of the meal of Little Owl have moved around somewhat and a dead mouse serves as a later meal. The third picture shows the rather messy Little Owl that was probably caught in the act of eating the unfortunate victim sibling. The fourth picture shows the smaller bird that crouched in the corner!

More Warblers

Another 0530 start saw Will and me at Rawcliffe Moss squeezing a ringing session into the promised window of weather. But at 0900 we took the nets down when a heavy rain shower came in from the North West and the wind picked up to put paid to our successful few hours.

We caught 35 birds of 8 species only, most of the birds either Sylvia or Acrocephalus warblers.

New birds: 1 Blackcap, 3 Sedge Warbler, 1 Reed Warbler, 1 Goldfinch, 1 Blue Tit, 1 Dunnock, 1 Willow Warbler and a surprising 21 Whitethroat, twenty of which were juvenile birds of the year.

Recaptures: 1 Sedge Warbler, 2 Whitethroat, 1 Dunnock, 1 Willow Warbler.

So the apparently successful year for Whitethroats and Goldfinch continues, and even though we caught only one Goldfinch this morning, there were plenty zipping around. But we discussed the spring and summer birds we haven’t been catching, seeing or hearing and which we normally expect in or near the plantation and woods out on the moss. While Goldfinches go from strength to strength Linnet numbers are not comparable with its close relative and it is now unusual to see large flocks of Linnets but not of Goldfinch.

On our last two visits in July the Willow Warbler numbers dried up a little, but August will tell if this is a momentary blip. Wrens are conspicuous by their absence; we haven’t caught one for months. Dunnock numbers are also down with probably one pair only in the plantation. On the farm as a whole Grey Partridge seem non-existent, and all three latter species are almost certainly missing as a result of the severe winter. Sometimes it’s not so much what birds are seen but the species absent that gives insight into the overall picture.

Other birds seen this morning were 2 Buzzard, 2 Kestrel and a single Sparrowhawk. 130 early morning Swallows may have exited a roost but the 10 Swift and 3 Sand Martins we saw later in the morning all headed determinedly south.

A Bright Interval

It rained most of the morning, but as promised by Diane on BBC Look North West the situation brightened towards midday. So I grabbed an early lunch then set out towards my local patches of Pilling Lane Ends, Conder Green and Bank End because there was a tide due about 1pm even though it wouldn’t be high enough to bring a lot in close.

There wasn’t much doing at Lane Ends itself, apart from the resident two Reed Warblers, singing from suitable distances apart. I reached Pilling Water without opening my notebook, waiting until I reached the stile to jot down just a hovering Kestrel and the 3 Little Egrets I’d seen from some distance away, conspicuously white against the green marsh.

At Pilling Water I settled down on the still wet grass and surveyed the marsh. There had been an obvious influx of Little Egrets, and I counted 7 of them, one towards Fluke, three along the ditch and three out on the water’s edge where amongst the Black-headed Gulls was an adult Mediterranean Gull again. Wader wise I counted 600 Curlew, 14 Dunlin, 3 Ringed Plover, 2 Common Sandpipers and 1 Greenshank, plus 2 Grey Herons, waders of sorts.

Also on the water’s edge I noted 5 Eider duck and 5 roosting Cormorant, plus Lapwings, but only about 40 today. I’ve been looking out for Wheatears again on the Wheatear rocks and today there was one, a single juvenile bird that went out on the marsh as I approached. Other passerines came in at 5 Linnets and 4 Skylark, and hirundines at 90 Swallow and 12 House Martin over the Fluke Hall Lane crop fields, plus 8 Swifts.

I spent a while at Conder Green, enough time to log the Ruff that has been around for a week or two now. Ruff are good that way, with individuals tending to have distinct features whereby it is often possible to say a bird is the same one as on a previous occasion. 4 Common Sandpipers, 30 Redshank, 1 Spotted Redshank, 1 Little Ringed Plover, 90 Lapwing, 1 Great-crested Grebe and 14 Oystercatchers were the highlights of my short stay.

Oystercatcher

Each time I have been to Bank End lately it resembled Piccadilly Circus with the comings and goings to the parachuting centre, but today it was quiet and I had the road to myself with alongside it 6 Pied Wagtail, 8 Tree Sparrow, 8 Linnet and 2 Meadow Pipit with low over the marsh 15 Swallow, 12 Swift and 10 House Martin. I watched a tatty looking Kestrel obviously in the stages of full moult as it struggled to hover above the road, periodically taking time out where it rested on the embankment. It looked better on the ground.

So once again I fitted one in between the showers and the grot, but how I wish we had summer back.

The Spice Of Life

There were one or two tasks to complete on the Integrated Population Management and Reporting (IPMR) database at Will’s house near Garstang, so because last night’s forecast was so poor we arranged to sit down at the laptop this morning, always keeping one eye on the weather of course in case a net or two might be in order. As it turned out the morning was cloudy with rain threatening but the drops never arrived so we updated IPMR and fitted in a spot of ringing.

If there’s one thing guaranteed in Will’s garden it’s variety, which turned out very true this morning when we caught an assortment of 34 birds of 12 species:

There were 30 new birds as follows:
8 House Sparrow
1 Jackdaw
4 Greenfinch
9 Chaffinch
2 Great Tit
1 Woodpigeon
1 Nuthatch
1 Dunnock
1 Robin
1 Blue Tit
1 Jay

With 4 recaptures: 2 House Sparrow, 1 Swallow and 1 Chaffinch.

The young Jay proved as feisty as an adult – beware fingers.

Woodpigeons are a much underrated bird. How beautiful is this?

I must admit that a Jackdaw isn’t quite the prettiest bird.

The adult female Swallow was a recapture as it breeds in Will’s shed and regularly flies through the garden.
