Nice! 🙂 What exactly does spp. mean? I’ve seen that and sp. around and I somehow still don’t know what it means. Is it just unidentified species?

Yes, sp. means a single species, spp. means plural species. Based on differing flight behavior and call notes, I think there were at least 2 warbler species and perhaps 2 sparrow species (but it’s possible they were warblers as well, they just looked a little big for warblers). I use sp. and spp. as shorthand for unidentified species.
