2011 Humpback Chub Translocations to Havasu and Shinumo Creeks
In June 2011, Grand Canyon National Park took another major step in the effort to restore native fish populations in the Grand Canyon with the release of 243 juvenile humpback chub into Havasu Creek. Translocations to tributaries may establish additional spawning populations of this endangered species in Grand Canyon or add to the number of humpback chub living in the Colorado River.

Second Humpback Chub Translocation to Shinumo Creek in 2010
In June 2010, fisheries biologists released 300 young humpback chub into Shinumo Creek in Grand Canyon National Park. This second translocation augmented the number of humpback chub in Shinumo Creek following the 2009 release. Biologists hope that Shinumo Creek will provide rearing habitat for humpback chub in a natural environment outside the Little Colorado River.

Crews defined camping pads, constructed trail and built fencing to define the parking area. The goal of the work was reduce human impacts to the area’s riparian vegetation and to enlarge the camp to accommodate two groups at a time. The project also was an opportunity for members of the private boating community to get to know park staff in an informal environment.

Archeologists Excavate Two Sites Along the Colorado River

Park Biologists Survey for Non-Native Brown-Headed Cowbirds
Park biologists located 500 nests of songbirds in Grand Canyon National Park in 2008. Biologists searched for the nests as part of a project aimed at understanding the distribution of brown-headed cowbirds in the park, a non-native species. Cowbirds don't build their own nests or care for their young. They lay their eggs in the nests of other bird species, possibly impacting populations of the park's native bird species.
