I have shot this picture at the Marshes of Caw.
We have approached one pair of White-headed Marsh Tyrants.
The female, being shyer than the male, was already gone when, located at the back of the boat, I have been able to find an angle of view to shoot a few pictures.

We have observed the pair of White-headed Marsh Tyrants close to this nest which is not exactly ovoid-shaped. Maybe it is still under construction.
