You’ve forgotten the Japanese, that stuff never breaks. Helps that they always have a family story of how at the blessing of the gods, 573 years ago they started a knife making business and now they either rule 7 prefectures as knife royalty or it’s one dude making knives in a tiny alleyway building. Either way that knife will last longer than you will.
I'm no expert on these and these are mostly based on vibes, not actual field marks. I'll give it a shot anyways.
1. Something with GWGU in it, Cooks Inlet maybe?
2-3. Might be Herring, looks kinds off for Western to me? mainly head shape
4. Glaucous-winged. (Or Olympic but wingtips are really white)
The main problem is that the goose was shot way before it arrived at the park, probably before it was even first discovered over 6 months ago. The bird is fully healed and is fully capable of flight. There is no reason to capture and “rehabilitate” the bird when there are Canada Geese at that same park in far far worse condition. The capture and transport of the bird causes far more stress than eating a bit of bread with the park geese ever did to that bird.
