Shrew and vole ID
Last summer I spent some time in the Alps (Arolla in Valais) and I caught some mammals that I find rather hard to ID.
This shrew was caught in a trap that I put up in a grassy patch bordering a shed and a grass field at the edge of the town (approximately 2000m altitude). The photos are quite crappy, but based on coloration and the hair on the hind foot I think it may be Neomys anomalus (Miller’s water shrew) – any thoughts? The tail seems a bit long for the water shrew and there was no water nearby, so maybe it’s Sorex antionorii – although the coloration doesn’t seem to fit for that one and I can’t find information on hairiness of the foot for that species. Does anyone have any thoughts?
This second one is probably even harder to ID with the photo I managed to take. I caught this one by hand. It looked like a juvenile. It was caught at about 2300m altitude, above the timber line on a mossy/grassy patch. I’m thinking Microtus arvalis (common vole) based on range and habitat, but maybe it’s Microtus agrestis (field vole) or even another species?
Thanks a lot!
