The population dynamics of the Warbler species differ from what's documented by Scott Sillett and colleagues one migration issues.
The Warbler species are non migratory species, while Scott Sillet and colleagues have been studying migratory species. The Warbler species were even taken to other islands, in some cases, in order to give them the security of additional breeding populations, this because their population dynamics is not a migratory one. The studied species by Scott Sillet and colleagues, on the other hand, have migratory population dynamics: they pass their Summer time in New Hampshire and and their Winter time in Jamaica.
