Nice work, a fun solve! All of your wordplay works smoothly and I have no qualms with any of the cryptic elements. 1A and 4A are my favourites. I think sometimes your surface readings are a little off (1D and 2D, say) and you can afford to be a bit more subversive with your definitions — e.g. if you’re using “contest” to define MATCH (as a noun), then use “contest” as a verb in the clue. Thanks for the puzzle, I look forward to more.
Glad you enjoyed it! I try and be simple with my definitions because it's what I prefer when solving, but I can try to throw in some more complex ones for you :)
I don't know if you've ever solved a puzzle by Liari (https://liaricryptics.blogspot.com/), but there's another bird-lover for you! 1A is my favorite. I think most outlets would frown upon 5A: deletions should be consecutive. (I know this because I've gotten flak about this before!) I agree with JWords that 2D probably needs some work as a surface. Using something like [feed] as a synonym might help.
I might check some of Liari's puzzles out, thanks for the recommendation! Good to know for 5A, was hoping dismembered would take care of that, but I guess not.
4A: tut + ti
5A: hero(-i)n(-e)
2D: cat + er
3D: on(i)on
