Another one from the annals of weird deaths. Believe it or don’t, wading birds sometimes get their toes or bill-tips caught in bivalve shells, they remain trapped, and they then drown when the tide comes in. Here is rare photographic evidence of this behaviour…
The bird is an adult American oystercatcher Haematopus palliatus [a live one is shown below, by Bear Golden Retriever, from wikipedia*], discovered on Cape Island, South Carolina, in June 1939. William Baldwin found and photographed the specimen, and later published it in The Auk (Baldwin 1946).
The bird had obviously gotten its bill tip caught between the valves of a Hardshelled clam Mercenaria mercenaria and it then drowned while caught. Scavenging crabs later removed much of the soft tissue from the neck. Baldwin (1946) reported that he’d heard of cases from local people where oystercatchers had died in similar fashion after getting their toes caught, but the bird killed ‘by’ the clam was the only case he had direct experience with. I haven’t heard of any other examples of this sort of thing and wonder if there are more out there in the literature.
* What is it with the eyes of certain waders (and pigeons) – what is that extra little blob they have anteroventral to the pupil?
Incidentally, I’ve only just learnt that the Hardshelled clam is also known as the Quahog – ha! I had no idea; this explains a lot.
