        I have a flock of chicadees coming to my window feeder -  check =
your bird book and see the differences between them - the black capped =
chicadee, the carolina chicadee and the boreal chicadee.  When I see one =
that looks like a carolina bird I always wonder if it really is =
different or if the white stripe on the back of the black capped bird =
has been lost.   I tend to think I have seen all three, as well as a =
fourth bird that is a black capped bird who has picked up more white =
than he should have.  I would not have examined the birds this closely , =
but  when they are in the window I can do so from the comfort  or my =
easy chair.

Roland,

  Hi Annabelle,

  =20

  As Kathleen has indicated, individual variation, though subtle, does =
exist among Black-capped Chickadees as with any species. However, unless =
it is a difference caused by an accident (e.g. the bird is missing a =
toe) or one caused by genetics (e.g. Some/many/all feathers lacking =
pigment) you need to keep in mind that those differences are transient =
and will change or disappear as the bird moults its feathers or the =
feathers wear or break. In chickadees the moult takes place mostly in =
the month of September and should be completely finished by now so any =
subtle differences  you see should be good for quite a while.=20

  =20

  Kathleen is correct. As with any type of bird marking, be it banding, =
wing tags, neck collars, color-marking of any kind, etc., a valid =
scientific research permit must be obtained from the Canadian Wildlife =
Service in order to carry it out.

  =20

  All the best,

  My experience of chickadees is that while they are very bold and are =
willing to come quite close to humans for food, I wouldn't describe them =
as friendly. I don't think they generally form a relationship with =
humans beyond "feed me!" I think they are found near humans so often =
(e.g., in backyards) because they are so willing to take advantage of =
the food we provide. And I think a chickadee coming close to a human or =
other large animal is pretty safe and not stupid, considering that they =
are so small and fast and hard to catch. I don't think anything bigger =
than a sharp-shinned hawk is regularly able to catch chickadees.

  As for identifying individuals, I've noticed that chickadees often =
have different markings on their bib patch. There have been several =
chickadees I've seen over the years that were distinct enough to =
identify reliably. For example, one had a really straight lower border =
and two white-speckled patches in the bib. If you can't identify them =
based on their appearance, I think you're out of luck.=20

  Bird-marking dyes do exist, but (correct me if I'm wrong, list) I =
don't think it's legal for anyone to mark wild birds in any way without =
a research permit.

  Subject: [NatureNS] a question

  Since the mammal questions I have sent remain unanswered I want to ask =
a bird question about Chickadees. Actually more than one question.  Are =
they really people friendly or are they stupid or can they just not see, =
or is there another reason for their being around so much?  Is there a =
way of telling them individually apart?  The only individual I can tell =
is the banded one when I see the band, perhaps there is a dye which is =
safe for the others?
