Garden Ringing - 15th June 2019

I haven't done any ringing in my garden since March, so this morning I decided to get the net out for a few hours (05:45 - 09.00). My main target was to try and catch some of the 20ish juvenile Starlings that have been feeding daily in the garden, along with several ringed adult birds. By the end of the session I'd caught 17 birds, including 8 Starlings (6 new birds and 2 ringed birds), 2 juvenile Dunnocks, 4 Greenfinches (2 adults and 2 juveniles), 1 adult Blackbird and 2 adult House Sparrows.

I was able to sex the juvenile Starlings using their eye colour. The male birds have an all dark eye, whereas the females have a pale ring around the eye.

The two ringed Starlings that I managed to catch were very interesting. The first bird was an adult female with a very well developed brood patch (indicating breeding), and, when I read the ring, turned out to be a bird I'd caught in the garden in 20th May 2018. It had a brood patch then too.

The second ringed bird was a juvenile, and turned out to be one of the four pulli I'd ringed in May in the nestbox on the side of my house (see here). This bird was the only one of the 6 juveniles caught this morning to have started its post juvenile moult, as seen in this picture below.

It could also be sexed as a female, using the eye colour.

Other birds seen. but not ringed, were Chaffinch (2;1 male and 1 female), Goldfinch (4; 2 adults and 2 juveniles), Blue Tit (1 adult) and Coal Tit (1  juvenile).
