My wife comes from North Sumatra and as she puts it “if we see a bird in my village we shoot it”. She had no interest in birds before moving to the U.K. last year, but already she is heavily into photographing them. Her longest stint in a hide so far is 10 hours, just doing woodland birds. Her goldfinch above is all her own work. She set it up and was in the hide alone all day while I got on with the real work of finding new subjects to photograph. 100-400mm lens at 400mm. 1/400th at F8. 800 iso. Canon EOS 1d Mk111. from a permanent wooden hide.
