Dragged this thread up because the Big Year challenge inspired me to total the number of birds, mammals, reptiles and amphibians I have seen. The list consists of species seen in five countries:
Birds- 229 species
Mammals- At least 40, with at least 3 possible and 2 as roadkill only
Reptiles- 16 species
Amphibians- 9 species
Also did some dividing up on the life list by country (species seen in more than one country is only counted in the first country it is seen in):
United Kingdom- 30 mammals, 154 birds, 6 reptiles, 5 amphibians
Belgium- 1 bird (common sandpiper, if you must know)
Germany- 1 mammal, 4 birds, 1 amphibian
Spain-7 birds, 3 reptiles
Costa Rica-9 mammals, 59 birds, 7 reptiles, 3 amphibians (narrowly missing a fourth in the form of a caecilian- still kicking myself over that)
I'm aware the numbers (especially with birds) don't add up, but the list is frankly too long to go through again
