Pink-necked Green Pigeon – iris

posted in: Morphology-Develop., Pigeon-Dove | 0

“I was watching a very compliant/friendly female Pink-necked Green Pigeon (Treron vernans griseicapilla) feeding on a fruiting Muntingia calabura (‘Village Cherry’). As usual, only took the green-yellow fruit and not the fully ripe or discoloured ones.

“Allowed me to stick my long lens up close in its face; I was interested to get some images of the iris (above, below).

“Once it had fed it promptly took a nap, despite my proximity. Note the beautiful double coloured iris, lavender-pink outside with a bright blue inner ring (see Wells 1999). The blue and pink can only be seen in certain lighting and postures; as Wells notes, the whole iris can look dark red, and that is the common appearance you see in the field (below).

“To sleep or feed the bird will close the eye lids (not nictitating membrane); the lower eyelid is larger (below). Note the yellow-green cere at base of the upper beak (above).
