I have been told that is an outdated method based on old freezers. Modern
freezers apparently don't have this problem and the Burke museum says they
prefer people don't do this due to the extra mass.

Additionally, I have been advised to put the bagged bird into a second,
larger ziploc bag filled with water, and freeze the whole thing. The bird
stays dry in the inner bag, while the outer bag protects it against freezer
burn that is a result of the thawing and refreezing cycle of self-defrosting
freezers.

Hi Tweets,
The Slater Museum on the University of Puget Sound campus in Tacoma is happy
to take dead birds. Common birds are often being used in education kits for
K-12 classes and others are put into the collection. I will put out a
special request here for Anna's Hummingbirds, as we have are currently doing
research on rapid evolution in Anna's. And as other Tweets mentioned, the
Burke Museum at the UW takes specimens as do some of the local Audubon
chapters. When you find a dead bird, put it into a ziploc plastic bag along
with a piece of paper with the date and locality and put it into your
freezer until you can take it to your local museum.
Thanks very much,
