1.      The Brookfield Zoo) has produced a great number of biological
interactives in their permanent exhibits.  I noticed one of their "Be a
Bird" devices at the science center in Pittsburgh.  The device was
credited to Brookfield in their display.  I'm not sure if they travel
part of their exhibit, sell duplicates, or had a special arrangement
with this museum.  Brookfield's main number is 708 485 0263.
2.      SciTech, a small science center in Aurora, IL has interactive
exhibits on the style of the Exploratorium.  Several sets have been
produced as traveling exhibits and are also available for sale.  While
most are physics concepts, a few are on other topics, including weather
and the physics of aquatic animals.  I don't have their 630 859 3434.
