Here's a question I came across that may stump some of Tweeters' experts in
hummingbird anatomy:
Hummingbirds within Apodiformes have a bilaterally paired oval bone, a
sesamoid embedded in the caudolateral portion of the expanded, cruciate
aponeurosis of insertion of m. depressor caudae. How many paired tendons
are supported by this sesamoid bone? Answer with a number.
(hint: extra points if your AI tool provides the correct answer).
