Missing thumbnail for certain species

[xconverge]

I am missing a thumbnail for just one species? (so far that I have noticed)

Corvus brachyrhynchos

Should be this image I believe https://en.wikipedia.org/wiki/American_crow#/media/File:Corvus-brachyrhynchos-001.jpg

I don't see anything that looks suspicious in the logs

Edit: Going back a few days most are populated, but a few others that are missing are:

Poecile rufescens
Calypte anna

Some birds will be excluded since their license is too troublesome to parse into something readable. In other cases the author information might be missing, which appears be the case for this image:

https://en.wikipedia.org/w/api.php?action=query&prop=imageinfo&iiprop=extmetadata&titles=File%3aCorvus-brachyrhynchos-001.jpg&format=json

Files with no machine-readable author

Not sure how to deal with these cases right now. Maybe we can work around it somhow or do some sort of author override list for certain birds 🤔

"if supplied"

to me looks like it is fine to still use the image and make the author check optional in this case

Wonderful! Perhaps we could add some logic to handle missing authors for creative commons licenses
