April 18, 2013: Seven River Watchers identified birds as they observed the wildlife at the Hornsby Bend Biosolids Management Plants’s treatment Ponds. The ponds have been a haven for migratory waterfowl on the Central Flyway for North American Bird Migration for the last 60+ years. Hornsby Bend, the most popular birdwatching site in Central Texas, is host of up to 356 species of birds in any given year. On a good full day of birding, it is possible to see most than 100 species of birds. Check out the Hornsby Bend Bird Checklist here.
