The YouTube blurb reads:
Unknown bird fishing @ Arcadia arboretum (L.A. County)
Recorded July 11, 2007While feeding the fish and turtles at the arboretum lagoon, a persistent unknown bird, (I know electronics, not birds) was going after baby catfish, feeding on bread.He (?) eventually caught one. (No video), but I do have a still photo, of the little fish in its mouth. (beak?)
Whilst on the subject of anhingas, it is a little known fact that for some years one was living in Exminster marshes in South Devon. Back in 2001 a friend of mine from America was visiting Exeter and spent some time with Richard and me. We took the mildly touristy river boad that goes along the canal from Exeter to The Turf Lock a pub out in the marshes. The pilot of the boat was a lady who spent every winter in the Everglades doing something involving manatees, and she pointed the anhinga out to us. That is certainly what it was, although no-one has ever mentioned it before or since...
(For those not aware of these peculiar birds, the lower piece of footage is of an anhinga from You Tube
