Geographic and Temporal Variation in Annual Survival of a Declining Neotropical Migrant Hummingbird (Selasphorus rufus) Under Varying Fire, Snowpack, and Climatic Conditions

Geographic and Temporal Variation in Annual Survival of a Declining Neotropical Migrant Hummingbird (Selasphorus rufus) Under Varying Fire, Snowpack, and Climatic Conditions

Rufous hummingbirds (Selasphorus rufus) have shown consistent declines in abundance since 1970, with an acceleration in this trend starting in the mid-2000s.Demographic data is needed to isolate possible drivers. We employ mark-recapture data to calculate sex-specific adult apparent annual survival, accounting for residency probability, within the coastal and interior regions of British Columbia, Canada between […]

Pollinator Project in Saguaro National Park

Pollinator Project in Saguaro National Park

Viridiana Orona, a 2021 Mosaics in Science intern, will be working on a pollinator project at Saguaro National Park in Arizona. Mosaics in Science is a diversity internship program and partnership of Environment for the Americas that gives opportunities for young adults to learn from and work alongside the National Park Service. As the Biology Monitoring Assistant, […]

The State of the Rufous Hummingbird: A report on a declining species

The State of the Rufous Hummingbird: A report on a declining species

Rufous Hummingbirds are a charismatic and remarkable migratory bird, and through their role as pollinators, they provide important ecological services across their range in Canada, the United States, and Mexico. There is a great opportunity for concerned communities, bird lovers, and conservation scientists to rally together to develop a full life cycle conservation strategy to […]

Hummingbirds & Fire: It’s Complicated

Hummingbirds & Fire: It’s Complicated

To inform future restoration efforts, we reviewed the known effects of fire and habitat management and restoration on hummingbirds in four key habitat types in North America. We examined seven species that most commonly occur west of the Rocky Mountains: Rufous (Selasphorus rufus), Calliope (Selasphorus calliope), Broad-tailed (Selasphorus platycercus), Costa’s (Calypte costae), Black-chinned (Archilochus alexandri), […]

Banding Rufous Hummingbirds in Alaska

Banding Rufous Hummingbirds in Alaska

Gwen Baluss, USFS, Alaska: The Rufous Hummingbird is Alaska’s only regularly seen hummingbird. Making an annual trip from as far south as Oaxaca State, Mexico and back, the species tops the charts for migration versus size in the bird world. It is a tough traveler, but biologists are concerned about the Rufous; in fact, one appeared […]

Hummingbird Workshop in Mexico

Hummingbird Workshop in Mexico

In January of 2020, the Western Hummingbird Partnership held a hummingbird workshop for individuals to learn or improve monitoring techniques, explore threats to hummingbirds, learn new education and outreach activities, and attend a hummingbird festival. The participants were able to meet and learn from Dr. Sarahy Contreras, professor and researcher at the Department of Ecology and […]

Tracking Hummingbird Migration

sarahy contreras

Between the icebergs and whale sightings, not many people visiting Alaska would notice the lack of Rufous Hummingbirds during the time that they are supposed to be abundant. But this is what Sarahy Contreras is working to change – her most recent project consists of tracking hummingbirds along their migration route throughout the Americas. The […]
