Yucatan yellow bat

I can't say for sure Mona, and from pictures of leaf-nosed bats suggested by AfriBtas, the ears and nose of these don't look alike at all? I've added another close up of the heads, maybe that will help. Otherwise, I still think that Gerardo Aizpuru suggestion is right on.

Mona, right now with the lousy WiFi here at work, I'm unable to check out your link. I'll have a look once I get home or when the connection here is better.

Thank you Mona!

I think Gerardo nailed it with his ID.

A closer shot added.

I'm really not too sure Mona. I'll crop one of the pictures to get a closer look and post it.

I'm in the same boat and I was quite lucky getting these shots. My sister spotted one flying in and told me I had just missed a bat. I went back down into the darkness to have a look and just pointed my camera at something dark on the ceiling. It wasn't until we had come back out that I zoomed into the pictures to find that there were 6 of them huddled together.

Thank you Mona Pirih!

Thank you for the ID Gerardo, been waiting for a while hoping someone would have an idea of what these were.

Thank you for the welcoming, guess I never made it back here to read the comments :(.

It was 28c that day, a few degrees cooler down in the catacombs of this old church. I think they just naturally huddle together, maybe to keep warm or maybe for the feeling of being safer in a close group?
