Nest Box 08
There are three main cavity nesting species here at the James Reserve:
![]() |
Violet-green swallow tend to have a clutch size between 4 to 7 eggs. It will take 14 - 15 days for the eggs to hatch once the mother starts incubating the eggs. Some eggs may not hatch because one of the parents is infertile, poor incubation (common with young females with little incubating experience) or the egg shell is week. Once the eggs hatch the young birds will not fledge from the nest for 16 to 22 days. If the food source is in plenty a violet-green swallow pair can produce a 2nd brood in the same nesting season.
Western Bluebirds tend to have a clutch size between 4 to 6 eggs. It will take 13 - 14 days for the eggs to hatch once the mother starts incubating the eggs. Some eggs may not hatch because one of the parents is infertile, poor incubation (common with young females with little incubating experience) or the egg shell is week. Once the eggs hatch the young birds will not fledge from the nest for 17 to 22 days. If the food source is in plenty a western bluebird pair can produce a 2nd brood in the same nesting season.
Mountain chickadee tend to have a clutch size between 5 to 9 eggs. It will take 14 - 15 days for the eggs to hatch once the mother starts incubating the eggs which begins with the laying of the penultimate, or next to last, egg. Nests are made of moss, bark, fur, plant fibers, and feathers. Once the eggs hatch the young birds will not fledge from the nest for 19 to 21 days. |

| On 6/21 the chicks were not moving. The reason for their death is a matter of speculation. It could possibly be due to temperature extremes or parental inexperience. It appears that the parents will try again because they have not abandoned the nest. | |||
