Ground-Tyrant 1

Ground-Tyrants are not easy
to identify. This is a Spot-billed
Ground-Tyrant. At the picture
you can see the yellow spot at
the base of lower mandible.
The best way (and only reliable?)
to seperate this species from
Cinereous Ground-Tyrant is to observe this spot.

Spot-billed Groud-Tyrant
from behind. All pictures
from Chiguata 31.08.07.

Last picture: Here you can also see the short white supraloral. The yellow spot at lower mandible is dificult to see at this picture.

Hej Tor-Egil

Rufous margins on flight feather and coverts is actually a good mark as well. Also Cinereous is much paler gray on the back.
