Hi, Naomi You ask a very interesting question. I hope I can help.
First of all, you are right in assuming that juvenile (baby) birds may have
feet and legs which are a different color than the adults. If you look at
North American birds as a group, you will find that many species have dark
legs as juveniles (usually dark brown to gray to black) and the legs of
the adults are somewhat lighter. Field guides rarely illustrate nestlings,
however, so it requires direct observation to confirm this. There are many
exceptions to this, however. Look at illustrations of immature Snowy Egret
and you'll see that the feet and legs are even brighter than those of the
adults.
Secondly, I'm not sure which species of "blackbird" you are referring
to, but as far as the North American species go, I don't know of any who
have yellow feet or legs as adults or juveniles. The most commmon black
birds in your area would be ravens, crows, Brewer's Blackbird, and Red-winged
Blackbird, all of whom have black legs and feet. If you are asking about
some non- native species, I have no idea. There are over 9,000 species of
birds in the world, and you can find almost any possible color combination
if you look hard enough.
Hope this helps. Spring is on the way, and the Neotropical migrants will
be moving north soon. Have you learned that many of the birds that you see
in the summer spend the winter months in Mexico and Central America?
Ask your teacher if she can find a copy of the latest issue of "Wild
Bird" magazine (March 95). It has a series of articles that I know
your class would find very interesting.
Good Birding
