Subject: [cobirds] Dunlin - Interspecies friendship?
The Dunlin at McLellen continues to hangout with the Killdeer. This is my
third trip and each time they have been together. Is their a mutual benefit
to this relationship? I would think they could both easily find food
without the other. There are coyotes at the lake. See photo in checklist.
Maybe 2 pair of eyes are better that one to help alert to danger.

Then there is the Brandt and the Greater White-fronted Goose that seem to
always be together at the Lone Tree golf club. Certainly there are plenty
of other geese to sound an alarm.

Maybe it is just a need for companionship. And since their same species is
not around, they have found another species. Other examples of interspecies
friendships?
