The recent sightings of the varied thrush and black-throated blue warbler behind the Base-Mar Center in Boulder raised a few questions for me. I am new to this list so my apologies if these questions are not appropriate for this forum.
I am curious about research that has examined spatial patterns of stray birds and their characteristics (e.g., relative to their numbers, life stage, sex, species, habitat) and as well as possible changes in historical patterns owing to human-caused factors. I’ll be grateful for references to pertinent studies. Willem van Vliet— Boulder, CO -- You received this message because you are subscribed to the Google Groups "Colorado Birds" group.
