The Restoration of the Island Fox
The Captive Breeding Program
In subsequent years as pups were born and reached maturity, they were assigned mates based on a computer program designed to prevent inbreeding in small populations, such as the fox, and maximize genetic heterozygosity (lack of similarity).
The success of the island fox breeding program is evident in data given in the 2011 Island Fox Meeting Report. Considering the northern Channel Islands exclusively, numbers that include pups are as follows: Santa Cruz, 1302; San Miguel, 516; Santa Rosa, 292.
As a result of research conducted during the captive breeding period, we now know that island foxes have induced estrus and ovulation, which is unique among canids and may be related to other distinctive features of their mating system. Island foxes differ substantially from wolves, the species perhaps best known for its complex social system, strong pair bonds, and solicitous parental care. All the canid species appear to be socially monogamous, but from there they diverge in terms of group size, degree of sociality, and age of dispersal of young. For example, male aggression toward females - something that appeared rather common even in the reproductively successful island foxes - is virtually unknown for other canid species, in which males tend to be very solicitous to females, especially during estrus and pregnancy. However, it is unclear whether this behavior is characteristic of free-ranging island foxes or merely an artifact of captive conditions. In another contrast with other canids, the reproductive rate was lower for captive-born island foxes, the opposite of what is usually observed in other canid species. This suggests that something, such as social experience during the juvenile period, might have been missing in the captive environment, something that apparently is less important to other canid species.
Reintroduction of the Bald Eagle
From 2002-2006, the Institute for Wildlife Studies (IWS) released 61 bald eagles on Santa Cruz Island. In 2006, the first known nesting attempts occurred in the northern Channel Islands. Two pairs of eagles successfully fledged one chick each from nest at Pelican Harbor and Malva Real on Santa Cruz Island. Since 2006, there have been successful hatchings and Santa Cruz and Santa Rosa Islands. As of 2012 there are over 50 bald eagles on the California Channel Islands and over 30 known eagles on the northern Channel Islands.
