Post subject:  Gull at night ?!?
Tuesday evening at about 11pm I was out in the garden looking for bats and saw a large pale bird flying fairly high; I did wonder for a moment that it might be a barn owl, but the loud gull-like squawk made me think differently! Has anyone got any ideas about this behaviour, are night flying gulls common? :?

Hi Libby,

Night flying gulls aren't that uncommon, especially near the coast, but Barn Owls also emit a loud shriek.

There is a nocturnal-feeder species of gull, endemic to the Galapagos islands called the Swallow-Tailed Gull.

Trev, thanks for that, I'm sure it was a gull because it was more of a squawk than a shriek!

Katherine, I suppose I could say that it was a Swallow-tailed gull and see how long it takes for all the really serious birders to get their replies in!! :twisted: :lol: :wink:

Hi Libby

Last year I attended a talk by some researchers from Central Science Laboratory who were using short-range radar to look at bird movements at night in relation to bird-strike risk near airports. I forget all the detail but they confirmed what a lot of birders strongly suspected/knew already, that there is a lot of bird traffic in and out of roosts at night.

Where I do my WEBS count, there are still significant numbers of gulls arriving at the Pit when light levels are falling sharply.
