More garden ringing...

Another weekend at home and so another opportunity to set the net in the garden. It's been so mild and sunny that it really looks as though spring is springing. I'd been putting out apples all week and hoped that this may attract a few thrushes or something else - sure enough, I have noticed a lovely male Blackcap in the garden all week - would I be able to catch him?

Saturday morning was a little disappointing, with only three birds caught in total. However, one of these was a lovely male Goldcrest, aged as a 2nd year bird by the shape of the tail feathers and as a male by the presence of orange colouration in the crown feathers. I have these diminutive birds in the garden all year round and I strongly suspect that they nest in a tall fir tree in the garden - they've been singing away all week.

Male Goldcrest

Male Blackcap
Sunday morning (net still up as I write this) is slightly more productive - after a stand-off for most of the morning, Mr Blackcap finally met his match and flew into the net - a small price for a week's worth of apples! This bird was aged as an adult due to the broad and rounded shape of the tail feathers and the absence of any moult limit in the wings. The black crown clearly identifies the bird as male.
Male Greenfinch

Female Greenfinch

A late flurry of action resulted in a lovely pair of Greenfinches, a male bird which I couldn't conclusively age (no moult limit and an inconclusively-shaped tail) and a 2nd year female.

Woodcock day roost...?

Whilst out on a site visit this morning in the north of Hampshire, I was tramping my way down a bank on the edge of a lightly-wooded stream channel when I flushed a Eurasian woodcock. As usual, the bird was well-away before I realised what it was, flying off to presumably settle down somewhere else on the site. The bird had clearly been resting (or feeding) up amongst deep leaf litter and soft streamside mud beneath a large oak tree - the ground was a dense carpet of oak leaves. Just out of curiosity I had a closer look at the spot where it flushed from and was surprised to see a little oval patch of bare soil, roughly woodcock-shaped, and with a fresh bird dropping at one (presumably the tail) end.

It struck me that I must be looking at a day roost or scrape which the bird had made whilst it spent the daylight hours in this tucked-away corner of Hampshire. I have done a little web-based research and can find no mention of such a feature. Do woodcock 'make' day scrapes??  I guess not many people consider paying attention to where a flushed woodcock came from and glance up for a fleeting glimpse of the bird's backside...

Apologies - stupid Blogger seems to prevent image rotation - this image should be rotated 90 degrees right...

And again...

As it's the weekend and the weather is fine I thought I'd leave the net furled overnight and open it up again this morning. Very cold this morning thanks to clear skies (amazing night sky though) and a less fruitful day in the end - perhaps this new net-shaped change in their environment has spooked the resident birds?

You easily forget what a stunning little bird a Blue tit can be...
The same goes for the Robin too
A total of six birds so far - a wren, a robin, a dunnock, two blue tits and a great tit. Have now stuck some old apples on the trees to try and tempt some thrushes in, although there is a noticeable lack of either fieldfare or redwing in the village. On the up side, the village house sparrows seems to be spreading and I have seen them venturing down this end of the street for the first time since living here. The local nuthatches also seem to be very active - their calls have been a constant background today, as have those of the very vocal great spotted woodpeckers.

Ringing again...

After a self-imposed break of several years I have at last started ringing again. Yesterday evening I set up a single 12m net behind the apple tree in the back garden, adjacent to the feeders which I've been filling for the last few weeks. Arising at dawn (after little sleep due to a feverish baby) I unfurled the net and awaited a trickle of birds.

Over a couple of hours I had a standard selection of typical garden fare - 2 blackbirds, three greenfinch, two blue tits, a coal tit, a dunnock, a robin and a great tit. 11 birds in all and I suppose not too bad for a relaxed morning at home. The expected pheasants, collared doves and woodpigeons failed to materialise which was a result.

My ageing skills are rusty to say the least but generally speaking I had little trouble with these birds. The only 'tricky' thing was the robin - I could find no obvious moult limit on the greater coverts, all being the same tone and shape. However, there were five small pale wedges to the outermost coverts. After checking with Messrs Svensson, Jenni and Winkler it appears that full adult birds can, and do, show several pale wedges to the greater coverts. The key is that these diminish in size towards the body, rather than forming a neat break. This feature, coupled with a dark interior to the upper mandible, broad and rounded tail feathers and a dark brownish eye led me to age the bird as an adult.
