Agriornis murinus
The Lesser Shrike-Tyrant (*Agriornis murinus*) is a small, enigmatic member of the Tyrannidae family, distinguished by its subtle, mouse-colored plumage and raptor-like hunting style. Measuring approximately 18-19 cm (7-7.5 inches) in length and weighing 25-30 g (0.9-1.1 oz), it presents a dusky gray-brown on its upperparts, contrasting with an off-white throat and belly that often shows faint streaking on the breast.

Primarily insectivorous, feeding on large insects such as beetles, grasshoppers, crickets, caterpillars, and moths, occasionally supplementing with spiders or small lizards.
This diurnal species is often seen perching conspicuously on low shrubs, fence posts, or wires, acting as an avian sentinel in its open habitat. Its primary foraging strategy involves a classic 'sally-strike' from an exposed perch, snatching insects from the air or pouncing on prey on the ground....
