Week 3- Day 1. The Field Trip

Note the different echolocation frequencies! Different species of bat!

Note the different echolocation frequencies! Different species of bat!

A late blog as we were out on a bat walk last night in Clonskeagh (Dublin Suburbs). Prior to the walk we spent time with Una (a pH student in the bat lab and an expert on Irish bats!)

We learned about the various 9 definite species of bat that are domiciled in Ireland and the ‘blow in’ species on a visit from the UK. It’s great to see a ‘cool’ use for the callipers, we are sick of measuring beakers and balls in school!

Calipers-more useful than you think!

Now I can tell the students that they are part of a zoologists ‘toolkit’ when identifying species based on morphology only. We actually measured the forearm of some preserved bats, identified the species using keys (way more cool than using them for Irish plants on the hockey field!)

We learned about the frequencies of echolocation and how to use the bat sensors to pick up the variety of species in one location. Really loved this talk, completely fascinating. The bat walk- totally amazing!!!!!!!!! If Santa is stumped for good gifts-a bat sensor would be a winner!!!!!!! Immediately we picked up a Soprano Pipistrelle- the first time I have actually seen the perfect outline of a bat flying over head!, there was no mistaking that it was a bat and not a sparrow. We also identified Leislers bat, the only elusive guy was Daubentens bat! Totally amazing- free and a great activity for holidays- buy a bat sensor!
