Chaff- and Greenfinches

My last post was almost 1,5 months ago, far too long ago! Now I have some time again and I will post some blogs again :)

The past weeks the weather has been very bad, with lots of rain and wind. I've done some ringing the last month in the garden, not much of interest but last monday I had quite a decent morning with Greenfinches and Chaffinches.

Lots of Greenfinches and Chaffinches have been coming to our feeders which is nice. Usually when I put up my net I catch a Greenfinch and then all the Greenfinches know the net and I won't catch them anymore during the session. Due to the dreary weather last monday the net was hardly visible resulting in an increase of Greenfinch catches. This gave me a chance to have a close look at them again. They're certainly not the easiest to age, so it's a nice practice to catch some. Chaffinches usually see the net very well, they fly towards the net and just in front of it they bend off..

I managed to catch:

Blue Tit 4 - 2
Chaffinch 3 -
Greenfinch 5 -
House Sparrow 2 -

Total 14 - 2

Compare those to the wing photo of this 1 cy male Greenfinch:
Greenfinch (Carduelis chloris), 1cy male; note the difference in the pattern/colour of the tertails, secondaries, greater coverts, primary coverts and alula's compared to the adult males.

I ringed three Chaffinches, 2 adult males and 1 cy female.
