As it came light there were a few Song Thrush and Redwing around but not as many as I had hoped for and I only caught 1 Redwing and 1 Song Thrush on the first net round. The presence of a female Sparrowhawk probably didn't help and it wasn't long before she found her way into one of the nets.
If looks could kill. Not the best pose but holding her cradled like a baby was the best way for me to get a photograph. |
'acredula' Willow Warbler 23/10/14. |
The wing length of 62mm was indicative of it being a female and it was carrying a moderate amount of fat (score 3) and weighed 8.2g. At first glance I thought it was an adult that hadn't moulted because the primaries and tail were quite brown and similar in colour to those of adults in late summer just before they moult. However I quickly realised we are in late October and not late July and that if it was an unmoulted adult the primaries would be showing much more wear and abrasion by now, in fact they would look rather shattered. It was a first year bird (1Y) and the colour and wear of the wings and tail were consistent with that age given the late date.
T1, T2, T3 and T4 on the left side of the tail (right in picture) had been replaced. |
1Y female Willow Warbler 23/10/14, the latest I have recorded locally by around 4 weeks. |
