    50 Years of Birding: In 2009, The AWU Center for Environmental Research and the Travis Audubon Society celebrated 50 years of birding at Hornsby Bend. Program details and early history...

    Special Report: Eric Carpenter's Big Year at Hornsby Bend. Eric's report on his 2005 efforts provides a lot of good information about Hornsby Bend.

    Hawkwatch: The Travis Audubon Society funded Hawkwatch for 9 consecutive years, but was no longer able to do after the 2008 count. Peg Wallace conducted the 2001, 2002, 2008 and 2009 Hawkwatches. The 2009 data are available online, as well as the data for 2008, 2007, 2006, 2005, 2004, 2003, 2002, 2001 and 2000.

    Monthly Bird Survey

    Second Saturday 7:00 am and 4:00pm

    Starting in 1999, the monthly Bird Survey has taken place at 7am and 4pm on the 2nd Saturday of the month. We meet at Hornsby Bend in the Center for Environmental Research at 7am for the morning survey [Coffee and donuts at 6:30am] and 4pm for the afternoon survey. All levels of birders are welcome - the survey is a great way to improve your skills since we form teams matching experienced and novice birders. In the morning, we have teams covering different areas of the Hornsby Bend facility and count numbers of all birds seen. We meet again around 11am to tally up the species. The afternoon involves looking for species missed that morning, and we go until sundown. If you'd like to join us for the morning or the afternoon or both just show up at 7am or 4pm. We meet at the CER building which is the first building at the entrance to Hornsby Bend. We'd love your help!
