GRACKLES: SANTA BARBARA, CALIFORNIA


© Corina Logan
Tequila - Adult male
Leg bands: Yellow / Purple - Sep 2014
He preferred to drop heavy rather than light objects into a water tube to raise the water level to reach floating food, and he changed his preference in a follow up experiment where heavy objects were no longer functional


© Corina Logan
Cerveza - Adult female
Leg bands: Blue / Orange - Sep 2014
She loves magnetism!


© Corina Logan
Charlie - Adult female
Leg bands: White / White - Dec 2013
Our first grackle! We banded her when she was a juvenile (her eyes were still brown instead of the adult yellow) and saw her grow into an adult. Her first breeding season was Mar-Aug 2014

Margarita - Adult female
Leg bands: Purple / Blue - Sep 2014
She also preferred to drop heavy rather than light objects and she loves magnetism too!

Michelada - Adult female
Leg bands: Orange / Red - Sep 2014
She was the fastest bird to learn to reverse a previously trained preference


© Corina Logan
Mojito - Adult male
Leg bands: Red / Green - Sep 2014
We banded and released him because the aviary was full at the time. You can see him in the wild flock with Tequila, Michelada, Cerveza, and Charlie at East Beach and the Santa Barbara Zoo

Chicha - Adult female
Leg bands: Blue / Red - Jan 2015
We banded and released her. You can see her in the wild flock with Charlie at East Beach

Batido - Adult male
Leg bands: Orange / Purple - Jan 2015
He preferred to drop heavy objects rather than light objects into a water tube and he hides under tables when raptors fly overhead

Horchata - Adult female
Leg bands: Green / Red - Jan 2015
She was the slowest bird to learn to reverse a previously trained preference


© Corina Logan
Jugo - Adult male
Leg bands: Red / Blue - Jan 2015
He always has a leaf or a piece of tape or something in his bill and he likes to put these objects in water

Refresco - Adult male
Leg bands: Purple / Yellow - Jan 2015
He preferred to drop heavy rather than light objects into a water tube to raise the water level to reach floating food, and he changed his preference in a follow up experiment where heavy objects were no longer functional
