What a wow of a shot - thank you for publishing it for us to see.
I am quoting from Frank B. Gills book "Ornithology" p. 148.
"...birds can flex or bend the upper half of the bill, an ability called
cranial kinesis. The maxilla of most birds flexes only at the nasofrontal
hinge. In some birds, the dorsal ridge of the bill itself bends -
rhynchokinesis- at the base of the bill, near the tip of the bill, or at both
sides. A woodcock, a longbilled, snipelike bird, can open just the tip of its
bill to grasp an earthworm deep in the mud.
Hope this satisfies your curiosity.
Cheers & Happy birding
