Update: The consensus seems from Lemmy and my friends seems to be European Starling. Thank you so much everyone. I was concerned on what kind of diet this fella should be fed, looks like I have somewhere to start now.
Having issues contacting the wildlife shelter at the moment
Now that you mention that I can probably guess where the nest was in our building. I hear birds chirping in our warehouse all the time.
They’re pretty loud in general so you would probably know, but they don’t tend be like to hang about indoors. Might just be house sparrows if you’re hearing them on the warehouse floor.
You should download the Merlin ornithology app. It’s built by the Cornell ornithology lab and has picture and sound ID features for birds as well as just a lot of generally useful identification information.
