The emergence of large bat colonies can be seen on Doppler weather
The bats inhabit the Waugh Drive Bridge over
Buffalo Bayou between Allen Parkway and Memorial Drive.
Parking is available at Spotts

from the sidewalk of the Waugh Drive Bridge or from the north bayou
bank, east of the bridge in Buffalo Bayou Park. Please observe quietly
