I have participated in a January bird count for the past few years. It is friendly "competition" which encourages me to get out during a long, cold month to look for birds in my area. My Ontario counts are very predictable, but this year I have spent the first eight days of the month in two very different parts of Mexico;- Nayarit and Coahuila. I have counted birds on the properties where my family live as well as one outing to the coast which included a boat ride through a mangrove swamp. Unfortunately I could not bring my binoculars and I really have to look for a good pair of travel bins. I have to look up a few birds when I get home so my count is unconfirmed at this time.
Many warblers winter here and I have been aware of them in the treetops but unable to get good views in the vegetation. Blue-gray Gnatcatchers are abundant but I have also identified a few Audubon Warblers and a Nashville Warbler. Perhaps I will have enough information in some blurry photos to add to this category of birds.
I have learned to identify a variety of doves during this trip. The dusty town where my daughter lives seems overrun with grackles, house sparrows and doves. The smaller Inca Ground Doves have beautiful plumage which blends in well when they rest under shrubs in the sand.
In Nayarit the White-winged and Common Ground Doves were more prevalent.
As far as I can tell, all doves sound pretty much the same and they are all well adapted to areas of human habitation. The last dove arrived in North America fairly recently from Europe. A few Eurasian Collared Doves were introduced the Bahamas in the 1970's and the rapidly spread in North America.
