COLUMBIDAE—DOVES. 215 all records of this species in Essex relate to either the Stock Dove or the Domestic Pigeon, which is descended from the Rock Dove.] Turtle Dove : Turtur communis. Locally " Little Dove." A common summer visitant, arriving about the end of April and leaving again in September. I be- lieve it is becoming more common than formerly throughout the county. Mr. Buxton says (47. 93) it is " a con- stant summer visitor [to Epping Forest.] I have seen flocks of them about Waltham- stow in late summer. Its plaintive note may be frequently heard in Theydon Thickets." Though usually a shy bird, I have known of nests in gardens quite in the town of Saffron Walden. Passenger Pigeon : Ectopistes migratorius. A very rare straggler to Britain from North America. A young specimen now in Walden Museum was shot between Chrishall and Royston in July, 1844 (37. iii. 27; & 38. 128). Through the kindness of Mr. Joseph P.Nunn, of Roy- ston, I am able to state that the bird was killed by the late Mr. John Norman of Knowns Folly Farm, part of which is in Cam- bridgeshire and part in Essex. Mr. W. Norman has assured Mr. Nunn that his late father had often pointed out to him the exact spot where he shot the bird, which was on some trees to the east of the farm-house. These trees stand in Melbourne parish, and are about 400 yards west of the Essex boundary ; but as the bird, probably, had crossed that boundary before being shot, and could easily have recrossed it in less than half a minute's flight, I consider it justifiably included here.
