A Tawny Eagle?
In "Love is For the Birds" Zuri and Tiffany found an egg that Tiffany identified as from a "tawny eagle". Wild tawny eagles are found in arid regions of Africa and Asia, very different from the climate on the Maine seacoast.
The only eagles found in North America are the bald eagle and the golden eagle.
So maybe Tiffany (Gasp! Shudder!) actually made a mistake. Or maybe she correctly identified a very out of place tawny eagle an ocean away from where it was supposed to be.
Or maybe this is yet another example of the Disney channel Live Action Universe being an alternate universe with a different biology than ours. Like the old time Tundrabanians in Liv and Maddie being able to collect enough blue whale bladders to outfit two teams, or alligators eating only live prey as the all knowing Olive said in A.N.T. Farm, or brown bears (Ursus arctos) being found near Miami, Florida according to the almost equally erudite Ally in Austin and Ally.
Possibly the out of universe reason is that the only tame and trained eagle available to be in the same shot as the actors without attacking them was a tawny eagle and it as correctly described as one in the dialog, even though they are not native to North America.
