Western Mexico Sinaloa, Nayarit, Jalisco and Colima from 21 February to 9 March 2019 by Dick Meijer and Peter van Scheepen Tufted Jay, Petaca road Presa la Colorada Introduction The scenic states of Sinaloa, Nayarit, Jalisco and Colima in Western Mexico offer great opportunities to observe plenty of fantastic and often colourful specialities. These include 52 (see table 1) of the 99 endemic species of Mexico and 55 (see table 2) of the 132 near–endemic (‘regionals’) species, as well as numerous wintering birds from North America, if you visit the area in winter. Western Mexico is extra interesting being a transition zone, where the southernmost representatives of temperate bird–families from North America (e.g. towhees, nuthatches and buntings) mingle with the northernmost representatives of neotropical bird–families from South America (e.g. woodcreepers, motmots, trogons and antpittas). Enough reasons for us (Peter van Scheepen and Dick Meijer) to ask Jesper Jacobsen (
[email protected] and www.jesperbayjacobsen.com) to offer us a trip with an itinerary enabling us to find most of these special birds. Our itineray focused on the well–known bird–rich sites near Mazatlan, San Blas, Ciudad Guzman, Colima and Manzanillo. It was quite challenging to identify the numerous wintering Empidonax– flycatchers we encountered with only plumage and structural clues and occasionaly helped by response to their songs and calls. To a lesser extent identification of the Myiarchus–flycatchers was challenging as well. The same applies to a few female hummingbirds, some of which could not be identified by us. We recorded 352 species in total of which 12 were heard only.
