Northern yellow bats are awesome creatures. At 28.3 grams, she is three times the weight of the velifer in the upper right of the photo. Check out those beautiful broad wings. We’re so lucky to have them in Austin! Let’s help them out by not trimming the skirt of dead fronds under the green crown of our palm trees. They have evolved to blend in perfectly with that habitat. They feel so secure there, that they are slow to awaken from torpor, and often plummet to the ground when the dead fronds are trimmed.
