Did you type a connection that was correct but not get the points you deserved? If so, sorry. The system isn't perfect. Do give yourself the extra points mentally. (There's probably no need to comment about this, unless it's constructive.)
Rustic: TL;DR - way too much possible crossing between categories.
A few points of criticism:
1. The loon is certainly not a songbird. Not by taxonomy, and not by vocalization. They call rather distinctly, but I don't think you'd deem it a song.
2. If taxonomy, then, is not the criteria for the songbirds list, then easily the p(ewe)e could swap with the ta(nag)er within the animal name category.
3. King(fish)er feels like a cheap answer within the animal name category, as it is by that very animal the bird was named. It's not as though the word is "hidden" in there.
4. A simple search of IMDb will yield film titles with many these birds (Loon, Pigeon, Cardinal) so the Oscar nomination is probably an important distinction to make the category solid - as (kit)e is another animal name, and the cuckoo, while not scientifically a songbird, also has a distinct call like the loon.
