Birding can take you to some rough old places....popped into Aylesbury early and had a quick stroll along the canal behind Tesco towards Broughton. Depressingly dirty with lots of accumulated detritus and dereliction. But from the 'buddleia forest' on the wasteland came the sound of a large goldfinch roost emerging at dawn. These places may offend our sensitivities but the wildlife always finds opportunity amongst what we discard or neglect. Caught up with a small group of siskins in the alders so mission accomplished.
