We saw this bird today at Orient SP today
A Lesser with a clear white head. I had reported a very similar gull, same area, same time of year, a couple of years back (It was swimming so no legs visible).
I was told at the time that it could not be a Lesser because the head was white and without streaking. I did not agree at the time - and now I rest my case:
Happy Autumn!

PS - It has been 12 years since 'our' Rufous hummingbird arrived for the beginning of her 3 month visit. So we keep the feeders up, and keep hoping for another.
