Fall migration in lower Arkansas Valley

I have been down in the lower Arkansas Valley of Colorado for the past week to enjoy fall migration. Last night a cold front moved through and there was a small "fall-out" of migrants at the Lamar Woods, a migrant trap behind Lamar Jr College. Among a number of Wilson Warblers were a Blue-headed Vireo (a rarity here), and two Warbling Vireos including the one in this pic. There was a flock of Cedar Waxwings that I heard several times before watching them fly over.

Sadly, this important neotropical stop-over is being taken over by more and more non-native weeds. Though the warblers and other landbirds use the very invasive Tamarisk and Russian-Olive trees that are there, there is an increase in plants such as annual kochia and grasses that do not provide good habitat.
