I looked up in the Key to confirm the origin of the eponym on Turdus merula cabrerae and found this:
● Dr Ángel Cabrera y Latorre (1879-1960) Spanish zoologist, palaeontologist, emigrated to Argentina 1925 (syn. Periparus ater vieirae).
● Dr Anatael Cabrera y Diaz (1866-1943) Spanish physician resident in the Canary Is., naturalist (subsp. Turdus merula).
Of course the second one is the person after whom the Blackbird is named.
But I was puzzled about the first one. What is the relationship between this name and Periparus ater vieirae? This subspecies of Coal Tit was named after Adriano Xavier Lopes Vieira, I can't figure out the relation to anyone named Cabrera...
