I posed the question above to the Western Cape Birding Forum
last weekend for the following photo of a Cape Rockjumper:
Except it was a trick question. The bird is in fact an
immature bird ringed in 2013 during our first round of Cape Rockjumper
captures. At the time I registered the bird as a youngster based on the brown,
not red, iris, buff wing spots and residual gape. But I also called it a possible
female and duly gave the bird a one colour identification ring.
This past season Gavin Emmons was helping Krista Oswald catch
more Cape Rockjumpers. He took the following photos of a splendid male – with yellow
ring. Thanks to the colour band we know he is the same bird from 2013! Very
exciting to get this resighting :)

Below is a photo of a juvenile Cape Rockjumper, probably only
1-3 months old, from the Swartberg Mountain range.
Note the black, not red, iris |
And this is how they start off life. Sad thing though: >60% of nests fail; which is pretty much the norm for ground nesting birds.
Not long now!
ReplyDeleteSo many interesting things in these photos. Even the rocks have caught my eye, the red inclusions ( ? or lichen?) are different
Yes - the red on the rocks is a kind of lichen.
