Rhyl, North Wales
Returning on Friday (13 Jan) from a wonderful couple of days in North Wales we called in at Rhyl Marine Lake. The adult Great North Diver still present, eventually came very close. Was able to watch a couple of lovely little behavior traits:
Swallowing a crab
Losing the Lump
First off the crab.
Diving non-stop for food it surfaced with this crab. Seemed to take a few moments to wash it off in the water before swallowing it whole. I am not sure but, the crab seemed still alive. Quite some feat! I think its a Shore Crab?
Now cleaned, just after this shot the bird turned away and swallowed the crab in one quick movement- amazing!
Losing the lump
Great Northern Divers variable show a big bump of lump on their forehead which at other times is absent leaving a smoothly contoured curved head shape. Here’s the lump showing well:
At such close range it was easy to watch the bump- presumably a set of raised feather- lowered just prior to the birds dive. You can see it happen on the video clip:
