So I found a bird. It could be a Passer sp. / Anthus sp. / Prunella sp. I dont know. I found it in the house, probably locked in when venting.
I drew a few conclusions and would like if I am wrong on any:
1st: It's an adult more or less, after all it can fly kinda and at this time of the year in the northern hemisphere nesting season is long gone. This is good, it wont get me ultra attached by some means of baby behavior.
2nd: Its unlikely injured, probably exhausted, confused and hungry.
3rd: It eats kernels and cereal (?) so I gave it a bit of what I found: Few dried fruit like cranberry and such, dry poridge and lentils with some ground haselnut I think. Along with water to get that down.
As FDK mentioned I hope that one night in a box with some food and water in a not too cold room might get it right back to life. I plan to release at dusk when temperatures will rise again, maybe a quick visual inspection before that to make sure its not injured.
Its hard to get a good shot of the little fella, when its standing up it looks slender elegant and streamlined, but it only does so to make a big leap so I couldnt catch that on cam.
