Jersey and New York had a later median egg laying date (mid-June) and significantly (p<0.05) smaller average early nest clutch sizes (NJ=2.67, NY=3.25) than those in an oak-hickory (Carya spp.) site, which had a median egg-laying date in early June and an average early nest clutch size of 3.88. Food availability likely explains at least some of the differences between the 2 habitat types. Eggs are incubated by the female for 12 or 13 days. After hatching both parents feed the young, which fledge 10 to 12 days later and are dependent on parental care for about another month. A wide range of eastern towhee nest success values have been reported. On Sanibel Island, 1 of the 5 eastern towhee nests observed was successful. In Louisiana, average daily nest success rate was 95.3% on a bottomland hardwood forest site. The same study found a 92.6% average daily nest success rate in a 6-year-old managed cottonwood (Populus spp.) plantation in Alabama. Average eastern towhee nest success across mixed bigtooth (P. grandidentata) and quaking aspen (P. tremuloides) stands of varying ages in Pennsylvania was 48.1%. In South Carolina, only 1 of 10 nests was successful, and the mean daily nest survival rate was 62.9%. This low value was explained by high levels of predation. Due to lower nest success rates of Bachman's sparrow (Aimophila aestivalis) than the previous year, it is suggested that eastern towhee nest success may have been measured during a comparatively poor year. Compared to nests, adult towhee survival rates are high. Average weekly adult survival rate of eastern towhees in a South Carolina study area was 99.3%. This rate was obtained from radio-marked eastern towhees and represented the pooled survival of both sexes and from 2 South Carolina sites, young and mature stands of loblolly and longleaf pine. Between 1962 and 1967 in Pennsylvania, annual survival of breeding eastern towhees calculated from mistnetting recaptures was 58%. According to a literature review, both males and females become reproductively mature in their second year. Eastern towhees of over 12 years old have been reported in the wild. Preferred habitat Eastern towhees range from near sea level to as high as along the border of Tennessee and North Carolina during the summer. A literature review reports eastern towhees up to in New Hampshire. Eastern towhees spend the majority of their time near the ground. For instance, in Pennsylvania in spring, observations
