Yellow eyes

We went back to Paxton Pits to do a bit more pruning around our net rides. While we were working in one area of the site, we set a couple of nets in a quieter part. We only caught 10 birds, but this young male Sparrowhawk (hatched last year) was one of them!

 

We also caught a few Long-tailed Tits, including a bird first ringed in autumn 2009, so it's now in at least its sixth calendar year (as a minimum). Not bad for a little bird that's been through some hard winters.

Where do birds come from?

Chiffchaff 'control'

Well, the obvious answer is 'eggs', of course. But after 18 months of bird ringing at home, I'm starting to get some interesting results - from birds I've ringed and which have then gone elsewhere ('controls'), or birds ringed elsewhere which I've then caught at a later date ('recoveries').

Before I went off to Canada, I managed to catch some warblers in a net over a ditch. Two of them were controls and another produced a recovery, which is pretty good going.

I caught a Chiffchaff which had been ringed as a young bird at Rye Meads the previous autumn, as well as the Whitethroat I mentioned in a previous post.

And I just heard about one of the Blackcaps I caught on 20 April. It had reached Rutland Water six days later, and they caught it again four days after that, by which time it had lost a couple of grams in weight so is probably breeding there. Fat is migration fuel, and there's no point carrying it around if you've arrived at your destination!

A couple of other birds have been less fortunate. A female Siskin ended up in the jaws of a cat in Sandy a few weeks later, while a Song Thrush lasted for another seven months before dying in unknown circumstances, also in Sandy.

Here's a map with the best bits so far.

Long-distance Clara

Female Whitethroat

Here's a bird with a little story to tell. This morning I caught a Whitethroat already wearing a ring (a 'control'). The number looked kind of familiar to me so I asked a few other local ringers if it was 'theirs'. It turned out to have been ringed near Tempsford in Bedfordshire, as a chick in the nest, back in June 2010!

When this information is crunched by the BTO, it'll say that the distance travelled between its nest and my place is only about 6km over slightly less than three years.

But in reality, it'll have made the journey from Bedfordshire to sub-Saharan Africa once in autumn 2010, then back the other way in spring 2011 and back again, probably the same in 2012 and has made it back again in 2013. So that's six journeys so far. Each time, it has to fatten up before leaving the UK, make its way through western Europe and through north Africa. For argument's sake, let's say it spends winter in the sahel in Senegal.

If it flew in a straight line directly there (which of course it won't have), that would be a journey of more than 2,700 miles each time. Multiplied by six, that's 16,200 miles! 26,000km!

The oldest known ringed Whitethroat was nearly seven years old, so this one has a way to go to beat that...

Another day, another Jay

Jay

Now seems to be a good time to catch Jays. I've had three so far this year, surpassing last year's total for the whole county!

North meets south

Chiffchaff 'control'

Some people reckon spring is at least three weeks late this year, and there are certainly some interesting combinations of birds around as spring migrants are slow to arrive, and winter visitors not keen to move back north.

This morning, the first bird out of my net was a female Brambling (below) - a garden ringing tick. And the second was a Chiffchaff control - that's when a bird has already been ringed by someone else! So it'll be interesting to see where it's been previously.

Up close and personal with garden birds

Siskin
With the tree seed (alder, birch etc) finally running out, Siskins are flooding into gardens. This male was a 'control' - a bird already ringed somewhere else when we caught it
Female Siskin
Here's a female Siskin - less colourful but still beautiful. See how fine the bill is for getting those seeds
Male Siskin
Another male, the first I caught in my garden
Lesser Redpoll
Here's another tree seed-munching finch, a Lesser Redpoll
Female Goldfinch
and a female Goldfinch
Female Nuthatch
Here's a Nuthatch, the third I've caught in the garden
Female Nuthatch
I 'retrapped' her 15 days later. Here's a close-up of the claws that mean Nuthatches can climb down trees headfirst
Treecreeper
I originally caught this Treecreeper on New Year's Day 2012, so it was good to see it's still going strong
Goldcrest
A Goldcrest, Europe's smallest bird, weighs about 5g (the same as 5 paperclips)

Jay meets Jedward

Jay
Look at my crest!

I caught a Jay in the garden this afternoon. They are gorgeous birds at any range, but when you're right up-close there's another dimension to them. As well as the dazzling azure blue of the coverts, there are tiny, hidden-away traces on the secondaries and the top of the tail.

Added to the constant, ear-splitting screeching and fierce biting and pecking, it's a feast for the senses. Just as well they don't smell nasty too.
