The Northern Waterthrush has larger regional populations than preliminary estimates
indicated.
Yellow-bellied Sapsucker: projected– most common woodpecker in northwestern CT, actual– 20,968 vs. 11,958 for the Downy Woodpecker.
Acadian Flycatcher: projected– 10,000, actual– 10,413.
Least Flycatcher: projected– 3,000, actual– 4,281.
Black-billed Cuckoo: projected– 1,000, actual– 411–815 in differing years.
Yellow-billed Cuckoo: projected– 1,000, actual- 2,156-4,354 in differing years.
Common Raven: projected– 400, actual– 395.
Cerulean Warbler: projected- 6,000, actual– 6,105.
Black-throated Blue Warbler: projected– 10,000+, actual– 41,712.
Pine Warbler: projected– 20,000+, actual– 74,431.
Louisiana Waterthrush: projected– 20,000, actual– 23,337.
Northern Waterthrush: projected– 3,000, actual– 4,190.
Eastern Towhee: projected– approaching 100,000, actual– 64,196.
Differences between initially projected and actual numbers are largely attributable to eastern Connecticut not always serving as a good model for populations in the rest of the state. This was particularly true in the case of the towhee, which had high densities in eastern Connecticut and Rhode Island but low densities elsewhere.
