|Grey-eyed Greenlet (Hylophilus amaurocephalus)|
Until recently the Grey-eyed Greenlet was considered a subspecies of the Rufous-crowned Greenlet (Hylophilus poecilotis) and still was when Ridgley & Tudor was published. However, several studies since then have concluded that Hylophilus amaurocephalus is a full species and a Brazilian endemic (see the article by M.A Raposo, R. Parrini and M. Napoli in Ararajuba, Volume 6, Number 2 of December 1998.)
|One of the features noted is the wide variations in plumage with the main features being a rufous crown, bright olive upperparts and buffy-yellow underparts. There is a darkish patch behind the ear which is much more pronounced in the Rufous-crowned Greenlet.
Despite its name, the colour of the iris is not diagnostic and can vary from grey to brown.
There are illustrations covering both iris colours in the Ararajuba article mentioned above.
