I have about 7 hours of video footage from my Werribee
visit, which I aim to condense to a 15 minute presentation in due course, but
have only reviewed about 3 hours of it so far. While videoing some
avocets I incidentally picked up about 2 seconds of an unusual gull that I take
to be a Black-tailed - grey smudges, black-tipped yellow bill,
short pale legs etc. I reported this to Birding-aus, and not surprisingly
got several requests to post images. As this might be of local interest,
I’ll do it here so the images are on our archive. The first image
below is an unenhanced video frame. The other 2 are brightened or
cropped. The video will appear of better quality but this bird probably
won’t make the final cut.
