Birds in the net

Early start - got up at 4.45am. Didn't get home til about 9.30pm. Between these times I was at Castor Hanglands, one of my old stomping grounds near Peterborough.

Juvenile male Sparrowhawk
For me, this was the highlight: a juvenile male Sparrowhawk. I haven't handled many birds of prey so it was a really good opportunity to deal with a bird that actually could hurt me - if it wanted to, and if I wasn't careful enough.

We got it out of the net without too much trouble, and put it in a cotton bird bag until we were ready to ring it. Then, I had to put my hand into the bag containing the hawk, and get the bird out again without letting it escape.

I could see the sharp talons sticking out through the cotton, so at least I knew where they were...

the eyes have it

Normally you identify the bird, put the ring on, and then do the ageing, sexing and biometrics (weighing, fat and muscle scoring, and measuring wing length).

With Sparrowhawks there's such a size difference between males and females they take different ring sizes (males being smaller). The wing length confirmed it was a male, and the chestnut-brown edges to the back and wing feathers show it hatched earlier this year.

The Sparrowhawk was surprisingly docile while I handled it. It had a look of rage in its eyes, though. When we were finished, it was a pleasure to release it. What a bird...

  1. I don't think I could have dared to get my hand that close to a Sparrowhawk. Fabulous photos.
