About two weeks ago we  heard a big commotion on our driveway and saw two parrots. We thought at  first they were fighting but it became clear one was dead and it seemed  the other was poking it, perhaps trying to wake it up. While my  husband went out to take a closer look, three parrots -- one adult and  two smaller ones -- flew and swooped over our yard. Later one came back  to the dead one, still trying to awake it up. Wildlife Rescue  picked up the dead one, but ever since, the parrots are in our yard a  lot, squawking and spending a lot of time in the tree right over where  the dead one lay.

 I've read parrots will mourn their companions, even starving themselves to death. Do you think this is what they are doing? Marty and Dick Johnson Campbell DEAR MARTY AND DICK: This is a really tricky subject because it requires walking the line between science and the heart. We often assign human emotions and reactions to animals, but researchers are split over how much emotional awareness they have. While  a number of creatures -- scrub jays, crows, elephants -- will gather  around their dead comrades in what appears to be a heartfelt showing of  emotion and sadness, scientists say it may be less about mourning and  more about warning. Studies have shown that birds gather around  one of their own and make a particular call that draws in more birds.  The calls seem to be warnings that someone or something has killed a  bird and that the entire flock needs to be aware of the danger. That  doesn't completely explain the behavior, however. There are plenty  examples of animals appearing to mourn the loss of a mate or a human  companion, and parrots, along with crows, are among the smartest of  birds. They may not have the brain size that humans have, but they have  demonstrated a variety of cognitive and social abilities. Their  grief may not be the same as humans, but I believe they feel a loss.  Parrots are monogamous and pairs share responsibilities. When one dies,  the other will eventually seek another mate out of practicality. As my  grandfather used to tell us, "don't pull in single harness all your  life," which means life is easier when you have someone to share the  burden. With all that said, I don't think the birds are staying around because of continuing grief. The  surviving bird may have relocated to your yard because whatever killed  the other parrot drove the bird out of its nesting area, or maybe  because it has found a new mate. Or they may have just taken a liking to  your yard.
