Bald Eagle Information and Guidelines
Bald Eagles at Corica Park Golf Course
Update: Bald Eagle egg(s) have been laid! More info below.
Bald Eagles are nesting at Corica Park golf course in Alameda, and we couldn’t be more excited about it! Bald Eagles, a symbol of our nation, were once rare in most parts of the US, including in the San Francisco Bay Area, due to pesticides, habitat destruction and hunting. Fortunately, they have made a tremendous comeback through environmental protections, including the banning of DDT. In recent years the Bay Area has seen Bald Eagle nests in Milpitas and at Lake Chabot, Ardenwood and Del Valle Regional Parks. Now a pair are tending eggs in a nest in Alameda in the middle of our dense urban Bay Area.
While Bald Eagle populations are expanding, these birds still need the support of conservation efforts, and continue to be protected by the Bald and Golden Eagle Protection Act and Migratory Bird Treaty Act. As of March 2023, the Alameda eagles have accepted some activities in the vicinity of their chosen nest, but careful precautions are needed through their nesting period.
Update: Our eagles have eggs! On March 1, for the first time, one of the GGAS monitors observed incubation activity in the eagles’ nest on the North Course, which has developed into their preferred nest. We have observed that one of the eagles is on the nest almost all the time, and the eagle tending the eggs is hunched down in the nest, frequently almost invisible except when moving. According to the Cornell Laboratory of Ornithology, the incubation period is 34 – 36 days. If we are correct about the date incubation started, and all goes well, the eggs would be expected to hatch in the first part of April. The nestlings will likely be invisible to us in the nest for at least the first 10 days after they hatch.
The typical number of eggs laid by Bald Eagles is between 1 and 3. We cannot tell how many eggs our pair is incubating. The pair shares parenting duties, switching places at the nest so each has a chance to hunt, eat and take a break.
The female of our pair has been identified by the Milpitas eagle watchers as Big Junior, who was hatched in Milpitas in March 2019. (Thank you, Milpitas!) The identification was made using some unique physical characteristics she has. This means she is young to be breeding, and this is very likely her first nesting attempt. …
