Upland Chorus Frog Video Portrait

May 2, 2010 in western Kentucky:

Major thunderstorms and gusty winds have raged across western Kentucky for the last three days, effectively delaying my work with birds. The one payoff: a couple of decent “frog nights” where I was able to collect some nice video and sound recordings.

On the night of May 1, I visited the Obion Creek Wildlife Management Area in the Mississippi lowlands near Milburn, Kentucky. There I focused my attention on a group of Upland Chorus Frogs (Pseudacris feriarum) calling from the edge of a flooded field next to the parking lot. Although a storm was blowing in and lightning was causing me some concern, I was able to get some very nice video clips (ultimately, a lightning strike nearby sent me packing!). Here are some highlights:

It is quite similar to the calls of a number of other chorus frogs, including the Midland Chorus Frog (Pseudacris triseriata) of the upper Midwest, the Boreal Chorus Frog (Pseudacris maculata) that ranges north into Canada, the New Jersey Chorus Frog (Pseudacris kalmi) found in New Jersey and surrounding areas, the Cajun Chorus Frog (Pseudacris fouquettei) of the mid-South, and the Southern Chorus Frog (Pseudacris nigrita) of the southeastern states. The calls of these species vary with regard to pulse rate (timing of clicks within a call), but they are exceedingly difficult to identify in the field because their pulse rates vary with temperature.

In the background of the video, you can hear a large chorus of Cope’s Gray Treefrogs (Hyla chrysoscelis). Here is the mix of sound of the two species, as I heard it when I pulled into the parking lot. Listen also for the occasional nasal calls of a single Fowler’s Toad:

    Excellent video! I love how they sing in such an upright posture. Here in southern Michigan, we have the Midland Chorus Frog, which is abundant during the breeding season here.

  3. We’re not quite sure what you’re asking. But, yes, we are conveying nature with considerable emphasis on the spiritual aspect of it, as opposed to just providing natural history information (although our web site is rich in natural history content). Musicofnature.org has been created to help people bond with nature. While our blog gives us a place to share our ongoing experiences, we also plan to secure grants for more specific projects dealing with our mission.
