Mitchell Lake Audubon Center - Bird-a-thon


The Audubon Center at Mitchell Lake connects people to nature and protects unique habitats. Located only fifteen miles from downtown San Antonio, the 624-acre property is a important stop-over location for many migrating shorebirds, waterfowl and songbirds. The drainages, ponds, wetlands, grasslands, and brushlands provide much needed food and shelter resources for an abundance of bird and other wildlife species. The diverse habitats also create an exceptional backdrop for a full range of educational experiences.

The Mitchell Lake Audubon Center (MLAC) has an average rainfall of 28 inches. The predominant vegetation of the uplands includes honey mesquite (Prosopis glandulosa), huisache (Acacia smalli), retama (Parkinsonia aculeate), hackberry (Celtis laevigata), granjeno (Celtis pallida), Brasil (Condalia hookeri), prickly pear (Opuntia lindheimeri), and others. The upland habitat of MLAC may at one time have mirrored the brush and grassland communities of the Rio Grande Plains Eco-region, however, past land use has influenced the composition of the vegetative community we see today. Non-native brush and grass species such as chinaberry (Melia azedarch), Chinese tallow tree (Sapium sebiferum), coastal bermudagrass (Cynodon dactylon), Johnson grass (Sorghum halepense), and others have replaced or out competed native brush and clump grasses. MLAC is working to restore native grassland to the property.

Water and its availability is a major influence in the diversity and abundance of plant and animal life at MLAC. MLAC has 3 distinct water bodies: a lake, polders and basins, and storm water ponds and drainages. All are eutrophic to varying degrees meaning that they generally have a high surface-to-depth ratio. Eutrophic water bodies also have an abundance of nutrients, especially nitrogen and phosphorus that readily stimulate a heavy growth of algae and other aquatic plants.

The Mitchell Lake Wetland Society (MLWS), an organization dedicated to the responsible stewardship of Mitchell Lake, currently has documented over 300 bird species at MLAC, of which more than 30 are on
Audubon's WatchList for Bexar County. Audubon's WatchList is designed
specifically to highlight those bird species that have the greatest
conservation needs. MLAC is especially important because of its
critical habitat for migrating shorebirds. Shorebirds utilize muddy
shores or mud flats to gather important food resources. MLAC is~he only site in the San Antonio area that has mud flat habitat vital to migrating shorebirds. Additionally, it is a major wintering site for migratory waterfowl.

Because of this, MLAC is a proposed Important Bird Area (IBA). Due to the efforts of the MLWS and others, an IBA proposal has been submitted to Audubon for consideration. The IBA program is a global effort to identify areas that are most important for maintaining bird populations, and it focuses conservation efforts at protecting these sites.

MLAC also has a diverse assemblage of reptiles, amphibians,
insects, and mammals and over 120 plant species. Studying the
interdependency of the plants and animals found at MLAC will help guide management efforts that will benefit the entire ecosystem for a more healthy environment for all.


In 2005, the concept of a Bird-a-thon was started to help raise money for the Mitchell Lake Project. Calvin Finch, Jerry Parsons and Milton Glueck were the KLUP- AM 930 fund-raisers. More information about this event can be found at:

Calvin Finch is busy looking for birds and Iliana Pena is busy telling him how and where to look.

Jane, the Curious Naturalist, points the bird out to legally-blind Calvin Finch and other on lookers.

This crowd is intense!! Their peering paid off with 69 species of birds spotted on this beautiful day. Having Andy Kasner (second from left in white hat) didn't hurt either; he is a keen birder. If you look closely, you will see Jane saluting the rare bird while Milton is hiding in fear (behind everyone!) of such a vicious fowl.


Milton Glueck with his single scope is no match for the intensity of Curious Jane and her binoculars.
