tetrapodzoology | May 22, 2009Here is a Secretary bird Sagittarius serpentarius skeleton I photographed some time ago: as usual, apologies for my terrible photography. The bird is lying on its back, and both its wings and legs are folded up. I would like you to concentrate in particular on its humeri: what the hell is going on?
Here's a close-up. Both humeri were like this. It looks as if they were broken mid-shaft, and then healed, but with the two halves of the shaft being totally misaligned (though I'm not saying that this is necessarily what happened: I really don't know). You might assume that a bird with injuries…

This informative video discusses the conservation of one of my research birds, the Rimatara (Kuhl's) Lory, Vini kuhlii, known by the natives as the 'Ura. Not only is this bird's story interesting, but it also exemplifies the complications and challenges of conserving any endangered species. This is part three of a three-part series [8:46]

tetrapodzoology | May 17, 2009
I try not to under-estimate the intelligence of my readers, but couldn't you be just a little more clueless? I mean, come on: virtually every person who left a comment realised that the 'mystery animal' from yesterday was a replica owl. Clearly, it was much, much easier than I thought. Anyway, well done everyone.
These owls are mostly based on Great horned owls Bubo virginianus, but the colour schemes are often a bit weird: the one I photographed has a red chest, though I doubt if this sort of thing makes much difference (hmm, or does it?). What's amusing is that this particular decoy is at…

tetrapodzoology | May 11, 2009It is with some sadness that I must pass on the news that Cyril Walker died last Wednesday (6th May 2009). Cyril worked at the Natural History Museum from 1958 until his retirement in 1999. He is best known for his many palaeornithological contributions: often working together with his colleague Colin Harrison (1926-2003), he produced numerous papers on fossil birds from all around the world. Among the more noteworthy of these are the pelagornithid review (Harrison & Walker 1976a) and the Prophaethon reappraisal (Harrison & Walker 1976b). Cyril also contributed to Charig et al. (1986…

Some of you might remember the remarkable photographs of the blue-colored male house sparrow, Passer domesticus, that was photographed in a garden in Sydney, Australia a couple weeks ago. I posted the images I had, along with my speculations, but was unable to go further than that. However, I tracked down the photographer and he has very kindly…
