The start of the main trail -- still pretty wet!

Hi Folks
Well at long last we have some bat data for you from last night! Hurrah. It actually didn’t rain on Friday or Saturday, but we couldn’t reach the trap locations because one of the streams we need to cross was still too high for us to get through without being chest deep in water! Even the main trail near the house is still pretty wet, as you can see from the pictures (glad I brought my rubber boots with me!)

But yesterday the stream had dropped and we were able to set and get to traps. The traps are still off the main study grid, and I have to confess I’m not entirely sure where they all are these days — we are continuing along the main trail, but there are also traps set on various little side trails that I’m not familiar with. Fortunately we had two of our Orang Asli workers with us (last night it was Mat Degu and his son Jamalruddin) so we don’t get too lost! So the traps set were KL0651, KL0652, KL0653, KL0654, KL0655, KL0637, KL0638, KL0639, KL0640, KL0641, KL0646, KL0647, and it was a clear night with no rain.

As you will see we caught our first Phoniscus atrox of the season; I’d be wondering where they had all got to! And one of the Kerivoula pellucida  escaped before we could get the measurement data (grrrr!). All the females were lactating, although it looks like a few of them are close to finishing, and the young are being weaned. That means we will probably start to see more juveniles in the captures in the coming weeks as they start to forage independently. So here are the data:
