lasts about 46–48 days with the female as the one doing the task. The male meanwhile provides all the food for this period. On average the young fledge at 50 days old (after hatching). Moreover, they stay dependent on their parents for an additional 6–11 weeks. It is late into the nestling period before the mother is able to leave the nest to go hunt and the father is no longer the sole provider of food for the family. In addition, there have been some accounts of a collared forest falcon feeding fledglings that are not his own. Little is known on why this would occur and/or how often this type of behavior is exhibited. Nests Collared forest falcons use the cavities of large trees and wood debris as their nests. All are non-excavated nesting sites, occurring naturally through decay or broken limbs. Nothing extra is brought into the nest as bedding or support. The entrances and nests themselves are quite large to accommodate for the size of the female birds. Furthermore, larger trees (dbh: 90 cm - 314 cm) are favored for that same reason. In this regard, Spanish cedar (Cedrela mexicana) seemed to be selected more often, in other words there was a positive selection for this species. Other species of trees observed to be used as nesting sites includes: Honduras mahogany (Swietenia macrophylla), Black Cabbage-bark (Lonchocarpus castilloi), Yellow Mombin (Spondias mombin) and Chicozapote (Manilkara zapota). Nesting in live trees proved highly more successful than in dead trees, which were mostly unsuccessful. Most breeding pairs will use the same nest site in subsequent years. Egg and clutch size The eggs of the collared forest falcon are a dark reddish brown with spots found to be either tan or dark brown. Clutch sizes are small, consisting of only 2 eggs. Mass of the eggs are an average of 53.4 g (+/- 2.6 g). Conservation Currently, M. semitorquatus ranks as least concern in conservation status since it inhabits a wide variety of forest types. On the other hand, the collared forest falcon tends to select bigger, old growth trees such as the Cedrela mexicana as their nesting sites. This type of wood also happens to be preferred by the surrounding logging industries. Future research may want to look into the potential impact that logging could have on the breeding of these large birds. Modified habitats may prove unsuitable for these
