Thanks for all that input which was leading me to a tentative conclusion until I started to check Ridgely's "Birds of Ecuador" Volume 1 (on taxonomy, etc.)
Here he mentions 2 races for Ruddy Pigeon: ogilviegranti
For Plumbeous Pigeon he mentions 3 races in Ecuador: chapmani
. But bogotensis
is a sub-species of Ruddy not of Plumbeous according to my references.
Checking all this with John Penhallurick's Bird Data Project at http://worldbirdinfo.net/
I find no mention of bogotensis
under Plumbeous and furthermore the fact that ogilviegranti
is a synonym for bogotensis
I also wonder if the pallescens
sub-species occurs in Ecuador since all other references seem to restrict this race to "southern tributaries of the Amazon from river Purus (which is at least 1000km east of Ecuador) to Para"
Which leads me to wonder how reliable Ridgely's "Birds of Ecuador" is with regard to these 2 species.
Googling "Columba plumbea bogotensis", the only hit is a Field Guides Trip List for Ecuador in 2003, presumably using Ridgely as its source.
I am confused.
