Hi all, I recorded one MAGW on the Mogollon Rim with Andrew Farnsworth 3 or 4 years back and then again recorded several in Oregon last year. Beleive me, not an easy bird to get good flight calls from! I will dig through the pile of calls and post some. It is MOWA like, but less rising and not as modulated. Andrew and I also completed getting a lot of other western warbler calls, we published spectrograms in the latest Auk, we will see about getting some of them together since there is some interest in them :)
Was out listening for awhile tonight in at Powdermill , not much even though a lot of activity in the late evening. Some light warbler movement, also VEERs, RBGRs, BAORs, some SWTHs too...
