Boswellia may stimulate blood flow in the uterus and pelvis. It can accelerate menstrual flow and may induce miscarriage in pregnant women. Other possible side effects of boswellia include: nausea; acid reflux; diarrhea; skin rashes
Bluebird nests usually contain four to five eggs. Clutch sizes range from three to seven. The number of eggs in a clutch is often related to the age of the bird laying them. First-time nesters often lay only four eggs.
Normally, bluebirds raise two to three broods per year, often using the same nesting site each year. The female selects a proper nesting site 4 to 6 feet above the ground in a cavity or hole excavated by another animal. The nest is a neat, cup-shaped structure made of fine grass. The female lays one egg per day for 4 to 6 days in the nest, and then incubates the pale blue eggs for 12 to 14 days. Soon after hatching, the youngsters sprout feathers. They have gray backs coupled with spotted white breasts and only a hint of blue in the wing and tail feathers at this time.
