A background on accomplishments, events, and lessons learned in my involvement in Eastern Bluebird population recovery. 2001 was my first season of Bluebird "farming". To begin with, here are the actual 2001 stats on the 4 pairs of nest boxes that were placed before mid May: |
| Babies | Eggs | Losses, babies | Losses, eggs | Notes |
| 17 | 30 | 0 | 13 | 9 eggs destroyed by English House Sparrows, 3 eggs abandoned due to Tree Swallow harrassment, 1 egg punctured by a House Wren |
| After the babies have left the nest there are many dangers that face them. Here are the estimated statistics on how many would return in the spring if hypothetically 100 babies were raised: | ||||
| Babies | Birds returning | Birds relocated or died | Mating pairs | |
| 100 | 50 | 50 | 25 | |
|
Just before 1970, only 10% of the all Eastern Bluebirds were left.
Insecticides, non-native bird competition, habitat loss, and some severe weather
were the causes. Nest box programs starting in the 1980's were major factor in bringing the Bluebird population
up to safer numbers and they are continuing to rise.
2002 successes: 58 birds:
37 Bluebirds(BB) fledged, 11 Chickadees fledged,
8 Tree Swallows fledged. Continued on page 2 with photos & data >> || Bluebird Feeder || Bluebird Info
