Delta-spotted Spiketail (Cordulegaster diastatops)

Last June we discovered a Delta-spotted Spiketail (Cordulegaster diastatops) along a busy road that turned out to be a first Chautauqua County record. This past weekend I discovered an individual of a new population at a second location in CHQ that Twan photographed here. We are hoping to record other spiketail species this spring and summer at a few more sites in the Chautauqua-Allegheny region.

Twan took the following photos of the Passenger Pigeon mount and study skins, Meet Your Neighbours...

Checking on the Limosa Harlequin Frog

Twan and I are currently checking in on the Limosa Harlequin Frog (Atelopus limosus) population in Panama in our continued effort to survey their health and status. This past January I visited them and brought back the great news that their population was still holding steady. During the time I surveyed them I found four adults, six sub-adults, and 17 metamorphs. I even found adults higher up in the preserve than previously spotted leading to the suspicion that the population may be increasing. This theory is something we are exploring and will try to confirm during this trip. When we...
