Kids will watch thousands of free-tailed bats fly through the sky at dusk, turn junk mail into art and learn how to identify hawks this month at the Houston Arboretum and Nature Center. Week-long Nature Trekker camps are for kids five to 12 years old. One-time events for families and adults don't have a cool name like Trekkers, but they're fun all the same. Times and days vary. Through June 26. 4501 Woodway. For information, call 713-681-8433 or visit www.houstonarboretum.org. $18 to $270.
Mondays-Fridays. Starts: June 2. Continues through June 26, 2009
