My family & I have visited the Colony twice, during the past few weeks, & we've loved it. The colony is comprised of ~250,000 Mexican free-tailed bat who live in the crevices in the underside of Waugh Drive bridge, which spans Buffalo Bayou. Bats are visible throughout the day, & emerge en-mass just around sunset to hunt.
The times of nightly emergences vary greatly. The Houston Parks & Recreation Department recommends coming 15-30 minutes before sunset, if you want to watch this, but on our most recent visit, yesterday, we arrived half an hour early, & the bats were already emerging as we were running frantically over the Jackson Hill pedestrian bridge. A volunteer speculated that the bats may have been especially hungry that night, b/c their last hunt had been cut short by rain. So come early, especially if it was rainy or cold the night before.
The bats return to Waugh Drive bridge around 5:30 AM, so be on the lookout for them, if you jog in Buffalo Bayou Park in the early morning.
Emergences are spectacular. The bats usually come from the eastern end of Waugh Drive bridge, skimming the bayou in a long train, before rising high into the sky in wave upon wave. Bat-enthusiasts watch from (1) the bridge, itself, for pics of the stream of bats following the bayou, (2) the Observation Deck, on the northeast corner of Waugh Drive & Allen Parkway to see the bats congregating, & warming-up for their long flight together, by flying in circles beneath the bridge, (3) the dandelion-shaped Gus S. Wortham Memorial Fountain in Buffalo Bayou Park, along Allen Parkway, just east of Waugh Drive. According to our volunteer, the bats often fly low, overhead, along the sidewalk near the bayou tree line, turning sharply upward to avoid the fountain.
Bat pups are born in May-June, & begin to hunt for insects, just 4 weeks later. Because of this, the most impressive emergences are usually in August & September, just after the little ones have been weaned & have joined the hunt.
Bat Chats are held on the first & third Friday of the month on the Observation Deck, & are worth attending. Volunteers are experienced & knowledgeable. Our volunteers had been giving talks here for over 7 years. Even after the emergence, they stuck around to answer questions; showed us a taxidermy bat, entombed in a clear plastic case; & shined a high-powered flashlight covered with pink-tinted cellophane into a few of the crevices, revealing the roosting mother- & baby bats who had remained behind. While there, we saw a hawk & a night heron catch & eat fallen juvenile bats. According to our volunteer, even large fish prey on fallen juveniles.
So stick around after the emergence. There's no need to leave, like a bat out of hell. When we stopped by the colony, yesterday, there were still many hundreds of bats gearing-up for flight, long after the main group had left. We watched their progress for nearly an hour, from the path that passes under the bridge.
Our group included adults & kids aged 2-8, & all loved it. The 8 year old declared she wants to have her next birthday party here. I was hoping she'd then proclaim, "Tonight, I'm Batgirl!", but no joy...Meanwhile, all of the older kids were all actively engaged & asked the volunteers lots of questions, while the adults fidgeted, & tried to stifle their own to give the kids plenty of time with the volunteers.
We all went, well, batty for the Waugh Drive Bat Colony (tee-hee). Sunset bat emergences are fun for most everyone. Inherently cool. Quintessentially Houstonian. Highly recommended, especially on the first or third Friday of the month, during the summer & fall.
UPDATE: Returned to the Colony (http://www.yelp.com/biz/bats-n-bites-uye-houston, http://www.yelp.com/events/houston-bats-n-bites-uye), and the rep from the Houston Zoo scheduled to give the Bat Chat didn't show. Boo hiss! Minus one star to you, Waugh Drive Bat Colony. read more
