Follow their adventures on Twitter #TheGrackleProject

Empanada - Adult female
Leg bands: Yellow (left leg) / Purple (right leg) - Banded in Jan 2018
She was very calm and a keen observer of human behavior when she in the aviaries in early 2018. In the wild, she does her own thing and particularly likes hanging out under a big shady tree on a golf course.

Fajita - Adult female
Leg bands: Purple / Blue - Jan 2018
She was an eager participant in behavioral choice tests when she was in the aviaries in early 2018: she was really curious and exploratory and was willing do anything for peanuts. Back in the wild, she settled in with a group of grackles that are nesting in two big pine trees near a soccer stadium.

She is a big fan of the traps and keeps revisiting them even after she was banded.

Quesadilla - Adult female
Leg bands: Orange / Red - Apr 2018
We don't see her around much. If you see her, will you email Corina and let her know where?
She is a traveler: after banding, we didn't see her for two months, and then she popped up 0.5 miles away from her banding location.

Flauta - Adult female
Leg bands: Red / Green - Apr 2018
Her projectile defecation led to us deciding to always use a towel over our laps when banding.

Tostada - Adult female
Leg bands: Blue / Green - May 2018

Naranja - Adult female
Leg bands: Orange / Orange - May 2018
A very vocal grackle who is a traveler: we saw her about 0.25 miles away from where we banded her. We saw her feeding her chicks potato chips.

Taquito is one of those rare grackles that were able to catch twice, so after we already had data on him in the wild, we were able to bring him into the aviaries and learn more about what this guy knows.
