Need some ID help. Over the last two days I've observed a large flycatcher at Pioneer Park in Princeton, MN. The bird is around eight inches or so in size, yellow wash on the stomach (which extends quite high on the breast), some white on the tertial edges. It has a slight crest (not pronounced), but (here's the rub) no apparent rufous on either the tail or wings. The head is quite dark.
In many ways it resembles Sibley's juvenile Great Crested, but without the rufous coloring. GC's do nest within the park (have had numbers from 2-7 throughout the summer in this small park). Speaking very subjectively, it's "jizz" is doesn't seem quite right for a GC - but I'm not a flycatcher expert by any means. Am I just looking at an unusual juvenile, or...? Seems to me to be a bit early for a western wanderer (Dusky similarities not withstanding). Thanks! Al Schirmacher
