Evening Grosbeaks over Littleton - rare spring occurrence in Arapahoe

[David Suddjian]

This morning I heard 2 Evening Grosbeaks calling as they flew north-northeast over Littleton Cemetery.  Evening Grosbeak is rare in Arapahoe anytime, but (per eBird) most of the rather few records are from late fall and early winter in October to December. eBird had three Arapahoe records from spring in April and May, but these were from back in 1984 and 1993. So today's birds are an exceptional spring detection, the only eBird report for the county in spring since 1993. I must say, they would have been very very easy to miss, with just a short series of 'tew' calls as they sped over, vocalizations easily overlooked among the other bird sounds.
