A cold morning out at farm just south of the A14. My first experience of whoosh netting. We set the net in an area of stubble that had been baited with grain, and within half an hour had upwards of 100 yellowhammers milling around.
They were obviously not that keen to go in front of the net though, but we did manage an initial catch of 13 birds, mainly aged 5 (BTO code for hatched previous year). A second catch was more disappointing, with just 1 more yellowhammer, and a single male blackbird.
