Western Bluebird Nestbox Monitoring - Totals For 2017


We SO enjoyed the nestbox monitoring and birds at the Duhig Road site.

Box #1: 3 Tree Swallow fledglings (between 7/10 and 7/18).
Box #2: Not used.
Box #3: Western Bluebird (predation of Bluebird evidence) and then Tree Swallow nesting evidence (using Bluebird feathers from predation), but no fledglings.
Box #4: 3 Western Bluebirds fledglings (between 5/26 and 6/5). Another 2 (or 3?) Western Bluebirds fledglings (between 7/10 and 7/18), 1 unhatched egg.
Box #5: 5 Tree Swallow eggs, (2 first appeared on 6/18), but they never hatched.
Box #6: 5 Tree Swallow fledglings (between 5/26 and 6/5).
Box #7: 4 (or 5?) Tree Swallow fledglings (between 6/11 and 6/18).
Box #8: 4 (or 5?) Tree Swallow fledglings (between 5/26 and 6/5; Jeff thought appeared sluggish on 5/26). Five eggs laid, and at least 4 nestlings were alive on 7/18, but 4 nestlings were found dead on 8/3.
Box #9. Four Western Bluebird chicks (between 5/21 and 5/23), 1 died. Three Western Bluebird fledglings (between 7/3 and 7/18), 1 unhatched egg.
Box $10: Not used.

Total Western Bluebird fledges: Box #4-3 plus 3, Box #9-3 plus 3: Total 11-12 new Western Bluebirds, from 2 different boxes.
