Type 4 is rare in the east - but this type is on the move with a report also 7/23 in Ontario.. Noticed these approaching RECR sounded different (more hollow) than the type 12 I am used to hearing in this area, so hastily made a poor recording which I sent to Matt Young from the Finch Research Network, who put this one at type 4 (Doug Fir) from the west. Faint recording - I never saw the birds/flock
