The Bicknell’s Thrush has a polygynandry mating strategy (Strong et al. 2004). This is when multiple females will mate with multiple males. Which results in several males fathering a single brood. All the males and females will work to raise the young, if the nest were to fail the females will often attempt to nest again (Goetz et al. 2003). The number of eggs in each nest range between 3 and 4, it takes about two weeks in northern areas for for the young to start fledging. There is usually only a single brood per breeding season (Rimmer et al. 2001). Females choose nest sites based on the amount of food in the area. The Bicknell’s Thrush breeds in areas above 1100 meters in elevation ( Rimmer et al. 2001). In its wintering ground, the Bicknell’s Thrush faces faces predation from introduced predators such as the Norway rat and the…show more content…
The other major factor that affects the Bicknell’s thrush is habitat loss (Citation). Another issue that affects the Bicknell’s Thrush population is contamination by mercury(Citation). The Bicknell’s thrush is an omnivorous bird. Its diet consists of arthropods and fruit (Townsend et al. 2012). In their wintering grounds the male Bicknell’s thrush are found in areas where the are more arthropods, where the females are found where there is more fruit abundant (Townsend et al. 2012). The Bicknell’s Thrush is a known night time migrant (Rimmer et al. 2001). It’s migration route is not well studied but it is believed to move along the east coast of the United States to the Caribbean. The Bicknell’s Thrush leave for their fall migration in early October (Rimmer et al. 2001). During their flight south the will stop at various areas for 6 to thirty three days (Rimmer et al. 2001). The Bicknell’s Thrush leave their wintering grounds in late april to early may, they do not stop at locations like they do during their fall migration (Rimmer et al.
