“…Cold, wet weather is known to inhibit foraging by adults, result in abandoned nests, or cause death (Criddle 1927, Weld 1932, Musselman 1939, Haecher 1948, Miller 1970, Scott and Lane 1974. Extreme heat may be fatal to developing Eastern Bluebird embryos and can severly stress young nestlings, thus resulting in lowered nest success (Musselman 1935, Laskey 1940, Thomas 1946, White and Woolfenden 1973.…”

The Eastern Bluebird (Sialia sialis) is a sec-structures built in the abandoned cavities unless an ondary (non-excavating) cavity-nesting spe-obvious disturbance (predation, inclement weather, cies that readily accepts nesting boxes, and conflict with other species) appeared to have many studies (Laskey 1943, Thomas 1946, prompted the move to a new site.

Nestlings were banded when 8 to 12 days size, and nesting success in various parts of old. Adult birds were captured with mist nets and its range. In the northern United States some a variety of manual and automatic traps attached to bluebirds are double-brooded; first nests are nest boxes. Although a few birds were caught and banded throughout the breeding period, most unusually begun in early spring and second nests banded adults were captured as soon as possible after are initiated during summer (Peakall 1970). their arrival in March and April. Banding early in the Many bluebird pairs, however, rear only a season was necessary in order to obtain complete single brood in either the spring or the sum-breeding histories because bluebirds may change termer, and do not attempt second nests (pers. ritories and nest sites in early spring (e.g., four different pairs successively occupied a single nest box observ.), perhaps because of a limited num-between 3 Auril and 13 Mav 1976). ber of suitable nest sites (Lack 1968:176, Most bluibirds left the' study ' area in winter; ar-Stewart 1973). rival dates for these birds (migrants) are the dates In this paper I examine bluebird nesting of initial sightings in the study area. An arrival date is not necessarily the date of territory establishment adaptations, particularly those relating to the (males) or date of pair bond formation (males and temporal organization of the breeding season, females). A few bluebirds (non-migrants) wintered and compare nesting performance in year-in and around the study area; I considered their arling and adult birds.
