Asked Questions about Robins: General Information
Q.
I think I heard a robin in England. Is that possible? While
in England a few years ago, it was around dusk and I heard the distinct
chirping of what I thought was a robin. And in the shadows of early evening
the movements as well were the robin we know here in NJ. But when I saw
the same bird in the daylight, it was a dark brown, almost black, with
no orange-red on it. Are they related?
A. No, you didn't hear an American Robin. What you saw was a European
Blackbird. (Remember the nursery rhyme, four-and-twenty
were baked in a pie? Those are the birds!) YES, they are very closely
related to our robin--actually in the same genus! Meanwhile, the Robin
Red-breast of England isn't at all related to our robin! Homesick Europeans
who settled in America named our birds for the ones they missed at home.
Our robin was bigger and duller than theirs, but was the closest thing
they could find to fit the bill, so to speak.
Q.
What
are the biggest dangers robins face?
A. Most robins die from cats, hawks, and other predators, from accidents
such as bonking into windows, car strikes, and electrocution, infectious
diseases, and poisoning. Insecticides can be very harmful to robins. If
you use lawn sprays, be sure that they don't have insecticides as well as
the weed-killing herbicides and fertilizers.

Q. I
have a robin in my yard that has a lot of white patches on its body. Is
is an albino?
A. There are many forms of albinism. A true albino robin has no body pigments at all, including
in the eyes. Birds lacking any pigments in their eyes have no protection from sunlight, and go blind when fairly
young. But if a bird has normal eye pigments, sometimes it can survive a long time with pure white feathers. A
bird in this situation is called a partial albino. So are birds that have white patches here and there on
otherwise normal-colored plumage. In some partial albinos, white patches are perfectly symmetric. In others, they
are more randomly arranged. Some birds are born partial albinos, and sometimes they develop patches of white after
traumatic events, such as being attacked by a hawk.
Some robins don't have any pure white patches, but DO
appear far more pale than others. Ornithologists call this condition leucism
or dilution. This is a genetic condition when birds produce less-than-normal
amounts of normal pigments.
