Birding Site Guide

Saltillo is a nice city with all amenities and makes a good base to visit these 2 sites. To get to Tanque de Emergencia, take a bus from the terminal (one left at 06.45) towards Concepcion del Oro and get off 43km south of Saltillo at the turn for the Tanque which is just a gravel road on the left. Birding is good along this road with many desert birds. Traffic is very light and you need to be lucky to get a lift. After 8km there is an old water tank and the endangered endemic Worthen's Sparrow has been seen around here in winter. Further on there was a small lake where I saw Sprague's Pipit. There are huge prairie dog colonies and I saw Golden Eagles and Northern Harrier. If you have your own transport, you turn left at El Cercado after 18.8 km and drive towards Hedionda Grande. Walking, you probably have to go another day. The turn-off for Hedionda Grande is 32km s of Saltillo but from there it is about 28km to the place where you can see Worthen's Sparrows. You can take the same bus from the terminal towards Concepcion del Oro and try to hitch along this road. Traffic is still light but better than the Tanque road. I failed to find Worthen's Sparrow at either site. Other months might be better. 45 species including 19 lifers.
