captainjack0000's Identifications

Continuing from earlier today and yesterday. Spent 5 hours total today looking for this bird. Got good looks but never good pics. Here is the best I could do. Was also able to watch it give scolding calls at the crown of a tree which is when I got these pics. They show one white wing bar, white spectacle with black eye line, grey head, and yellowish underside.

The organism was found dead after most likely running into a predator. It was sunny and relatively hot out, the external gills on the the organism appear to have been removed by ants which were crawling on the corpse.
Class, Amphiba: Tetrapod with moist, scaleless skin.
Subclass, Lissamphibia: Extant amphibian.
Order, Urodela: Elongated body and tail.
Family, Sirenidae: Small forelimbs, costal grooves, and it presumably had external gills which were most likely eaten.
