torcases is incorrectly written, and should be written as "wood" being its meaning:
Plural of wood, term derived from the latin " torquis - is " that means necklace. This adjective is applied to wild, larger pigeons than urban, because on both sides of the neck, they have two white spots as imitating a necklace. Lately they are acclimatised to the city, far as installed in parks and gardens expelling acclimated as Blackbird species. In my neighborhood of Madrid made a year or two that are not heard Blackbirds sing or seen and yet every day there is more wood-pigeons whose scientific name is columba palumbus. Palumbus in latin means palomo and paloma palumba which probably comes from the Greek peleia.
