Birding Site Guide

The once extensive Lerma Marshes, w of Mexico City have mostly been 'reclaimed' as farmland. One remaining patch is near the small town of Almoloya del Rio, 20km from the city of Toluca. They can be visited in a day trip from Mexico City. Buses to Toluca leave from the western bus terminal called Poniente, which is next to the metro station of Observatorio. Buses leave every 5 minutes for Toluca and the ride takes a little over an hour. At the Toluca Central Camionera, ask around for buses to Almoloya del Rio. Some buses do not go all the way. Check with the driver whether they go to Atizapan or Atenco and follow the directions after that in the site guide. The altitude is 2,600m, 300m higher than Mexico City. Take it easy, bring plenty of food and water. The sun can also be very strong so bring sun block and a wide-brimmed hat as there is no shade. Follow the instructions in the site guide. The endangered endemic Black-polled Yellowthroats were relatively easy to find and responded well to playback. 40 species including 6 lifers.
