2nd Annual Bat Night
Well the rain stayed away for this years Bat Night and it was GREAT!
Around this time of year in Arizona we get nectar bats coming to our hummingbird feeders. The type of bats that visit our feeders are called Lesser Long-nosed bats (Leptonycteris curasoae yerbabuenae) . This species listed as endangered under the federal Endangered Species Act. Both last year and this year we signed up as part of a study that keeps data on bats that visit hummingbird feeders in the area. We monitor the feeders and record on a webside when we saw bats at the feeders and how much the sugar water level dropped that night.
For the past two years we have been lucky enough to have the bat biologists come out to our house an trap a few bats for the study. If you would like to see last years post, follow this link http://www.blogster.com/margar3t/bat-night-with-us-fish-and-wildlife The biologists set up mist nets around the feeders. Lesser long-nosed bats actually have pretty good eyesight and often avoid the nets.
Here our first bat caught in the net. This year we had bat biologists from both U.S. fish and Wildlife and Bat Conservation International (BCI) come out to trap the bats.
Once the bat is out of the net, the biologists look it over to check its over all health. I can never get over how small the bats look when they are not flying about.
Here is a close up of one of the bats. This one is female. One of the things the biologists wanted to collect was pollen, but none of the bats they caught had any noticeable pollen on them.
These are little bat flies. They are a parasite on the bats. I think these are Streblidae, but I am no bat bug expert.
A close up of the bat fly.
A close up of the wing while the biologist checks for health and age.
They measure the bats, also take their weight.
Then they dab them with a little magic marker so if the same bat gets caught in the net the same night, the biologists will know and just set the bat free.
All the data is recorded and then the bat is done, the biologists let the bat go to fly off in the night.
Here is another bat, also female. Four bats were netted, three were female and the fourth escaped out of the net before it was captured.
A close up of the bats face. They have lots of hairy whiskers. The claws you see would be the bats thumbs.
A close up of the underside of the bat’s mouth. In this photo you can easily see the leaf-nose.
If you look at a bat’s wing then look at your own hand you can see that each bone in the wing is similar to each bone in your fingers. Bat’s wings are like giant webbed hands with arms attached.
Note the arm, elbow, forearm, thumb then all the fingers coming off from it, making up the wing.
Another close up of a bat. It is not often I get a chance to see a bat so close up. They are amazing looking.
Kind of a profile shot here. Again you can easily see the leaf shaped nose.
This bat is starting to look like he is getting tired of ‘Bat Night’
Well, it is late. Time to close up shop. The biologist is carefully untangling a desert marigold that got stuck in the trap.
Above you can see the pole that hold up the net. But it is late and time to put everything away until next Bat Night.

I did enjoy it. And I'm glad to hear Willy is back to his old self again. His hair will grow back, and he'll be looking for his next adventure soon I'm sure. |
Thanks, the U.S. Fish and Wildlife biologist may use some of these photos for a presentation, how cool is that? VERY! We will have to take Willy on an adventure to put on the blog. |
Thanks, I always have a blast on Bat Night. I always learn something and it is so interesting seeing these bats so close up. So glad you enjoyed the post. |
Thank you, so glad you enjoyed it. Bat Night is always loads of fun for me. I don't think the bats enjoy it as much as I do though.:) |
It would be cool to see them up close I think, but I sure wouldn't be holding one any time soon. lol! |
Cool pics Margar3t! I wouldn't be brave enough to hold one though! LOL:) Glad the rain stayed away for this event! Jenn |
This is way cool! Never seen a bat this close up in a picture before! Must be a fun job to have as a biologists (at least in this field!). Ha those bat flies got free transportation! LOL |
always fascinating meg. i hope it is still a thrill for you. it's certainly a privilege to me that you share your experience. thank you. |
Thanks for the info meg. I really do intend on investigating...I would be thrilled see one at a feeder. |
Wow, M! Amazing pics, and info was great. Little bat flies? Who would have guessed. Thanks for sharing |
What an incredible experience to see them up close and learn more about them first hand. GOOD FOR YOU! |
Thank you, I had such a blast. I got to touch not only one but two. They are so darn cool! I love bat night! They are kind of fuzzy, wooly and soft. |
LOL! I looked up bat flies. There are they say 800 species! http://www.wyomingbioinformatics.org/~kdittmar/BatFlies/batfliesoftheworld.html Now this biologist is really serious about bat flies! http://www.buffalo.edu/ubreporter/archives/vol39/vol39n13/articles/DittmarFeature.html |
ROTFLOL! Yes it is! I think they do go on forever! I am willing to bet there are those out there they have no knowledge about. You are welome. |
LOL! So true! I had never heard of either until you post...but then I did not know there were tha many types of bats! |
:) I always seem to find the more I learn, the more I find out I have a lot more to learn. I only recently found out there were so many species of bats they make up close to 20 percent of all the mammal species, rodents top them. Bats are of course not rodents. Bats are in the order of Chiroptera which come from two Greek words, cheir "hand" and pteron "wing." Winged hand. :) http://www.untamedscience.com/biodiversity/animals/chordates/mammals/bats How is that for cool stuff you didn't know, but maybe you did and I didn't. :) |
If you go to the link , they have a big illustration of a bat's wing you can see how closely it resembles our hand, one less finger but so cool. Bats are really amazing. But then again, when ever I really look into anything it becomes fascinating. I wish I had way more time and a way, way, way bigger brain. :) |
I will as soon as they finish the laser treatments on my eyes and I get glasses. YEA! It is working! |
Excellent about the teeth. Bummer that she is still having reactions but good you figured out what may be causing them. Great about your sight. That has to be wonderful news! |

How very interesting. Now I probably know more about bats than most people I know! See how much we learn here :-) Tell Willy hi for me!
