Sylvia – another unusual visitor

Like a lot of other folk I gave up making new year resolutions a long time ago because the resolve would normally last until the 2nd or 3rd of January before slipping quietly unnoticed into the flotsam and jetsam of recent history, never to be seen again. But for 2013 I made two resolutions – the first was to get current with my wildlife diaries which have been appallingly neglected for far too long – and the second resolution was not to condemn the first one to the black hole into which it would normally be swallowed. And so far so good, hence I’m feeling rather pleased with myself.

This years listings can be found here at ‘Histon Wildlife Diaries 2013‘ and if you notice gaps of more than a couple of weeks opening up please feel free to leave a pointed reminder that I need to get my finger out and get up to date!

As a consequence of my girded up loins and renewed efforts I’ve been spending more time peering into the garden to see which creatures are in residence. Just before Christmas I saw the first blackcap in the garden, it was a male with his coal-black cap, like a judge about to hand down the ultimate sentence, and he stayed for all of 2-3 seconds before zooming off into the sanctuary of our neighbours orchard. And of course I was very pleased with this visitation because it’s always good to welcome a newcomer.

Then a couple of weeks ago when the winter weather was at its filthiest here in Cambridge a female appeared and spent some time refuelling on my fatball feeder:

The birdcam used to be around 6m away from where it is now but there were very few takers for the lardy delights on offer.  But since I moved it to its current location it has been busy every day with numerous bird species. The reason for the change is the lack of cover in the original location which left the birds exposed to the possibility of predation by the local sparrowhawk. But now they have cover within a metre or so and and I can sit and watch them all in close up on the TV. And one of the first to arrive after I moved it was my lady blackcap, who you’ll have immediately noticed has a rufous brown cap, not the blackcap of the male. The specific name ‘atricapilla‘ means ‘blackcap‘ and the Danish name ‘munk‘ means ‘monk‘. I wonder which godly habits gave him that name, or is it simply his ecclesiastical bonnet?

She arrived early on a murky morning, fed quickly and left, and that was the last I’ve seen of her. But a couple of days later a male blackcap arrived and he’s been visiting several times a day every day ever since then:

I’m puzzled as to why the female has been so conspicuous by her continued absence, I guess that now the weather is considerably more pleasant she is more comfortable feeding out in the countryside.

The male doesn’t restrict himself to ground feeding on fruit but is a more regular visitor to the fatballs.

And he tops up with water too. In the picture below he is wary of the goldfinch nibbling niger seed on the adjacent feeder. He was also aware of my presence behind a glass door around 8m away and when the goldfinch disappeared he threw numerous glances in my direction, but so long as I remained still he wasn’t too bothered.

Until recently it was thought that the blackcap was a migrant breeder here in the UK and that they spent their winters in Africa, apart from a sub population that remained here in the winter. But it is now thought that all of ours overwinter south of the Mediterranean and our winter visitors are a separate population from central Europe which migrate here to overwinter. In which case my visitors will be heading back east in the near future. After that I’ll hopefully see and hear our migrant breeders out in the hedgerows where they make a distinctive call which I think sounds like someone flint-knapping.

The British Trust for Ornithology have published a factsheet about blackcaps and their migration behaviour which is worth a read. We also have passage visitors as Scandinavian birds head south and it appears that garden bird feeders are having a major impact on the behaviour of blackcaps and other species too, such as nuthatch, which are now spreading into Scotland, assisted by garden feeding and climate change.
