Agriornis micropterus
The Grey-bellied Shrike-Tyrant (*Agriornis micropterus*) is a robust and striking member of the Tyrannidae family, a group known for its diverse flycatchers. Measuring approximately 23-25 cm in length and weighing 50-60 grams, this species exhibits a dull grayish-brown plumage on its back, contrasting with a pale, often faintly streaked grayish-white belly. Its most distinctive field mark is its stout, hooked, shrike-like bill, perfectly adapted for its predatory lifestyle, alongside a relati...
Found primarily in open montane shrublands, puna grasslands, and dry steppes of the Andes, often near rocks or scattered bushes. It typically breeds at elevations ranging from 2,000 to over 4,000 meters, descending to lower elevations in winter.
Its diet consists mainly of large insects such as beetles, grasshoppers, and moths, supplemented by small vertebrates including lizards and rodents. Foraging primarily involves striking prey from a prominent perch to the ground.
The Grey-bellied Shrike-Tyrant is a diurnal predator, frequently observed perching conspicuously on rocks, fence posts, or low shrubs, surveying its surroundings. Its foraging strategy is characteristic of a 'shrike-tyrant': it primarily employs a sit-and-wait technique, sallying rapidly to the g...
The Grey-bellied Shrike-Tyrant exhibits a wide, though somewhat disjunct, distribution across the high Andes of South America. Its breeding range extends from central Peru, southward through Bolivia, Chile, and Argentina, typically at elevations between 2,000 and 4,500 meters in arid puna grassla...

- The 'Shrike-Tyrant' name isn't just descriptive; it highlights a fascinating case of convergent evolution where a New World flycatcher developed a bill and predatory habits strikingly similar to Old World shrikes. - They are known to occasionally impale their prey on thorns or barbed wire, a be...
