4 Warbler species (listed below) are trans-Gulf migrants which, WJS hypothesizes, are blown off their normal trans-gulf migration routes to Yucatan Peninsula by strong winds from the N.E and which land in Los Tuxtlas by using the Sierra de Tuxtla as a “beacon.”  These 4 spp. Winter here as follows –

1. Dendroica tigrina – 17 September – 8 May.

2. D. caerulescens – 5 October – 17 November; 9 April – 3 May – 7 Winter records.

3. D. discolor – 28 March – 20 April; September – early October.  41 winter records.

4. D. palmarum – 19 September – 27 April.  47 winter records.

By comparing the maps for these species in Howell and Webb, 1995, it can be clearly seen that the normal wintering grounds are on the Caribbean coasts of eastern Mexico and N. Central America, except that D. discolor also occurs wintering in South Florida and D. palmarum also winters across the Northern Yucatan Peninsula.
