I had assumed that it was something like waterboarding, and the pigeon did die of drowning.

The gull knows that he can't outfly a pigeon, and has to rely on stealth and surprise. Difficult to be sure about the cause of death, but a severed spinal cord is quite likely. I have watched big gulls pecking things open with surprising force.

Thanks for your kind words about the blog. For the last few months I have been using a new lens, a Pentax DFA 150-450mm zoom. Although shorter than the Sigma 150-500mm, it gives much sharper images and my ability to photograph distant objects properly has increased. Half the weight and a quarter the price of the Canon equivalent, but every bit as good optically.If Pentax do a 600 or 650 in the same series, I shall be round at the shop the day it comes out.Ralph Hancockhttps://www.blogger.com/profile/11686354797977020917noreply@blogger.comtag:blogger.com,1999:blog-8278510471239667560.post-66985335441663531882015-11-13T02:37:17.265+00:002015-11-13T02:37:17.265+00:00Raphe, the gull last year was walking and stalking...Raphe, the gull last year was walking and stalking on the ground, while people were feeding the pigeons. Maybe it learned to get them from the back while drinking water from the lake, but last year, it was stalking on the ground, then walked the hapless pigeon to the lake, and basically pecked it to pieces. I wouldn't say drowning was exactly the cause of death. https://www.flickr.com/photos/johannacalifornia/15298942360/in/dateposted/Johanna van de Woestijnehttps://www.blogger.com/profile/16045404955308369929noreply@blogger.comtag:blogger.com,1999:blog-8278510471239667560.post-54957150764716125562015-11-13T02:19:32.085+00:002015-11-13T02:19:32.085+00:00I'm so sorry we won't be in London again s...I'm so sorry we won't be in London again soon, since our work there is finished.

It does indeed seem possible that the gull has learnt how to kill its prey without the need to drown it. In my experience -- and I have seen several other attacks that I didn't get a picture of -- the gull has always grabbed the pigeon by the back of the neck. I don't know whether this is from some innate killer instinct or simply because the neck is a fairly narrow and grabbable place.<br /><br />From what I have seen I think that the gull's most successful technique for initially catching the bird is to wait until one carelessly strays close enough for a grab from a standing position. I have seen this succeed several yards from the water, after which the gull quickly carried its victim into the lake. But it would also realise that a drinking pigeon is vulnerable.<br /><br />The gull developed this method after trying some less successful ones, such as dropping on to a passing pigeon from the restaurant roof or divebombing it in flight. Pigeons have faster acceleration from a standing start than Lesser Black-Backs, and a greater ability to dodge quickly.Ralph Hancockhttps://www.blogger.com/profile/11686354797977020917noreply@blogger.comtag:blogger.com,1999:blog-8278510471239667560.post-70880731886299133252015-11-12T22:46:30.081+00:002015-11-12T22:46:30.081+00:00Hi Ralph,

Eventually it got one – in the same circumstances I’d seen it successful before. The victim was isolated, supping from the Serpentine with its back to the gull and the gull grabbed the pigeon’s back or part of it between its beak. They spilled into the water together but the gull briefly returned to the edge of the lake with its catch to get a securer grip. It didn’t leave go of the pigeon, it just pushed its beak further into the flesh, and then took to the water again, where it continued for a minute or so pushing in the same way. Its beak seemed to rise up towards the neck of the pigeon which indicates I think that it was getting deeper and deeper. After about a minute of this treatment the gull let go and paused with the pigeon floating in front of it, conscious and immobile. The pigeon hadn’t been submerged at any point during this process and was moving its head from time to time and the gull’s beak had not emerged once. At this point I left, not wanting to see what I saw about a year or so ago when the gull ate a pigeon alive.<br /><br /><br /><br /><br />Josephhttps://www.blogger.com/profile/10529596094957534682noreply@blogger.com
