They perch among the highest positions to allow better surveillance. They have been observed chasing rocks thrown by people to attack them thinking they are intruders 😅.
I miss him so much, I hope to see him and that you can see him this year💞
This small, moderately abundant, and widespread shorebird has the broadest and southernmost breeding distribution of all the Nearctic Calidris sandpipers.

Social bonds are short-lived, and females may change nesting trees and social partners within or between breeding seasons.

Populations from central Canada and northward are often migratory, but may winter in Alaska when food is available. It is a very representative bird of prey of the culture of Mexico, so much so that it is the protagonist of our National Coat of Arms.
Seen flying quietly over forests and farmlands. It is the most widely distributed scavenger in the New World.
It is the only New World sparrow known to breed cooperatively; up to seven individuals attend the nest.

Changes in crops and farming practices have led to an increase in cowbird populations. Very curious watching me 😍
Most of their diet is based on larvae of wood boring beetles. They probe the trees, pick out where insects might be, and drill to extract them. They can even pry them out.

It was Allan Phillips who provided a breakthrough in identification that made it perhaps the easiest species of Empidonax to identify in the field, when he described its habit of moving its tail in a gentle downward motion, similar to the slow wag of the tail. of a Sayornis, instead of moving its tail up and then down like other Empidonax do.
I love them, they make me very innocent ❤️
The species is from forest habitats, mainly pine and oak, at least 2,500 meters above sea level. Surprisingly little has been published about its ecology, behavior, or reproduction.
