Heysham Obs
A male Brambling was by the feeder next to the office mid-morning. Interesting Twite paper in R & M begs the question as to whether there are biometrical differences between the most southerly and most northerly Scottish birds. Need to analyse our wing-lengths, but 'impressions' have always been that rather a low proportion of males and females can be clearly separated on wing length compared to e.g. Linnet and that surely cannot be due to a higher proportion than we thought of smaller Pennine birds 'muddying' the issue as this would surely have manifested itself in more Pennine captures/Pennine ringed birds caught here? If there is a variation throughout the Scottish range, would this explain our rather indeterminate data as 'our' birds seem to originate from anywhere between Lochinver and Sanda?
Lots of uncooperative Pink-feet in difficult-to-watch fields to the north of Heysham Moss this morning (thanks Janet for alerting me but unfortunately the 'easy' ones were flushed)
