On Monday 30 March, by chance I spotted a bird through the patio window, in an instant I identified it as a fully feathered and fledged Siskin.
I decided to make a dash for my tripod to make a video of this quite remarkable sight. I was eventually able to combine two videos of the bird in the Willow and then on the feeder.
After I had processed the video's and got to grips with the date and data regarding the Siskin, I quickly realised the significance of a young bird seen on the 30 March, which was at best highly unlikely.
So I was in touch and made enquiries with BTO - British Trust for Ornithology - and received a very comprehensive and much appreciated reply, a few important bits about the issue I have highlighted here.
'It was completely understood why you had thought this bird to have been a 'youngster', being puffed up and downy, and looking lethargic. But several members of the BTO team having viewed the video, the general consensus was that this bird being void of a gape was a adult female Siskin which had probably contracted trichomonosis'.
The author of this reply told me of a conversation with a another member of BTO involved in Terrestrial Ecology, has given three dates of earliest records of Siskin, one being, '4 live eggs 25 March 2010'.
Conclusion.
The best conclusion I can offer on this issue of a young Siskin in late March in our Lancaster urban garden is....With data I have, the earliest I could expect to see fledged Siskin is the end of April, obviously at least 4 weeks later than I thought one was in our garden on 30 March.
Taking into account, none of the footage could be rated as quality, I fail to understand how it could ever be labeled by anyone as an adult female Siskin, and it's my conclusion that the bird I found in the garden on 30 March was a stunted juvenile Siskin.
I welcome comments that contradict this claim.

It's really fluffy. So cute.
ReplyDeleteQuite agree with your fluffy and cute sentiments Sami, but what the bird actually was remains the overriding factor.

Pete - The video looks good quality to me. I wouldn’t like to say but fair play to you for trying to find out. Wonder if we will ever know for sure?
ReplyDeleteThanks for keeping us all posted.

Good enough video quality for the record Ian, and everyone will have to call the bird what they think, but I won't be changing my opinion.
