Probable Lawrence's Warbler, Blue Hill Trail, Sherburne NWR, left hand side, just before conifer section. Similar to Blue-winged, see Sibley pg 428, second to last backcross, little stronger eye line, 5 note repetitive call, followed by upswing trill.
This intergrade Golden-winged, Blue-winged area produces many interesting hybrids; one wonders how many pure bloods reside here. Olive-sided still present, many Dickcissels. Second half of Blue Hill still closed due to water issues. Please note new email during sabbatical. Still basking in Blue Grosbeak emotions.
