Chihuahuan Raven
Scientific Name Corvus cryptoleucus
Category D
Taxon Birds
Climate Change Vulnerability Score Less Vulnerable
View on BISON-M

The Chihuahuan Raven (Corvus cryptoleucus) is a large (46-53 cm [18-21 in] long; 442-667 g [16-23.5 oz]), all-black bird with a heavy, straight bill. It is omnivorous and opportunistic, eating live insects, worms, vertebrates, and roadkill. It also eats the eggs and nestlings of other birds and agricultural crops. Its habitat is very dry grasslands and deserts. It occurs in parts of Arizona, Colorado, New Mexico, Texas, and south into Mexico. The Chihuahuan Raven will experience a high degree of climate exposure and has a high adaptive capacity. Overall, it has a Climate Change Vulnerability Index ranking of Less Vulnerable under both Representative Concentration Pathway (RCP) 4.5 and RCP 8.5 Scenarios. The Chihuahuan Raven’s climate change vulnerability is impacted by movement factors, which influence its ability to shift in space.

Threats and Conservation Actions

Result for: All
Biological Resource Use Pollution
Assess the synergistic effects between climate change and other threats to SGCN and their habitats (e.g., Friggens et al. 2019, Parks et al. 2019). Incorporate appropriate climate adaptation strategies and frameworks into projects designed to address these synergistic effects. This may include enhancing connectivity (CEQ 2023), facilitating a species’ innate adaptive capacity (Thurman et al. 2022), enhancing genetic diversity (Powell 2023), considering local adaptation (Meek et al. 2023), or considering whether it is most appropriate to resist, accept, or direct ecosystem transformation (Lynch et al. 2021, Stevens et al. 2021). Projects should acknowledge ecosystem dynamism and incorporate indigenous knowledge (e.g., Roos et al. 2022, Eisenberg et al. 2024), nature-based solutions (Warnell et al. 2023), and experimentation (Guiterman et al. 2022) when appropriate. Potential collaborators: BLM, NPS, USFS, USFWS, USGS, universities, Tribal natural-resource managers.

Pollution
Determine effects of, and implement actions to mitigate negative effects from, agro- (e.g., neonicotinoids, other pesticides) (Sanchez-Bayo 2021, EPA 2023) and petrochemicals, synthetic chemicals (e.g., per- and polyfluoroalkyl substances [PFAS]), microplastics, urban runoff, and other pollutants (e.g., sewage, nutrients, toxic chemicals, sediment) on SGCN, especially fish and pollinating insects, and their habitats. This includes solid waste that may entangle wildlife. Potential collaborators: EPA, NMDA, NMED, universities, local governments, municipalities, private industry.

Biological Resource Use Pollution
Determine life history needs, ecology, distribution, movements, status, and trends of and threats to SGCN (especially invertebrates that are not currently monitored, riparian-obligate species, herpetofauna [Pierce et al. 2016, Olson and Pilliod 2022], and rare native fishes) and their habitats. Consider full annual cycles for migratory species when appropriate and logistically feasible (KFF 2021) and interactions with lower trophic levels that may drive SGCN status (e.g., EPA 2023). Use this information to develop and implement effective monitoring protocols and conservation actions, including actions to mitigate identified threats. Potential collaborators: BLM, BOR, NPS, USFS, USFWS, SLO, universities, non-profit organizations, private industry, species working groups, Tribal natural-resource managers.

Biological Resource Use
Enforce laws that protect SGCN populations that are often collected illegally, especially reptiles and amphibians. Longer-lived species, such as turtles, may be especially threatened by over-collection (Fitzgerald et al. 2004). Potential collaborators: BLM, DOD, NPS, USFS, USFWS, SLO.

Pollution
Evaluate and mitigate the effects of air pollution from industrial activities, including methane released by flaring associated with oil and gas extraction and leaking from old oil and gas wells, and in urban areas on SGCN and their habitats (e.g., Duque and Dewenter 2024). Evaluate and mitigate the effects of other types of pollution, including excess generation of heat, light, and/or sound from industrial activities, urban areas, and highways on SGCN and their habitats. Potential collaborators: BLM, EMNRD, NMDOT, NMED, energy and mining companies, municipalities, utility companies.

Biological Resource Use Pollution
Evaluate the effectiveness of public education and outreach efforts regarding threats to SGCN and their habitats and the ways that the public can assist in threat mitigation (KFF 2021). Modify outreach activities as needed in response to evaluation outcomes. Potential collaborators: BLM, BOR, NPS, USACE, USFS, USFWS, USGS, NMED, NMSP, SFD, SLO, universities, local governments, municipalities, non-profit organizations.

Biological Resource Use Pollution
Identify or develop an accessible, jointly used database to document the status and condition of, threats to, and conservation actions implemented across aquatic, riparian, and upland habitats. Identify data gaps (e.g., Ganey et al. 2017) and implement standardized methods to gather habitat data (e.g., Vollmer et al. 2018, Shirk et al. 2023) and to monitor the success of conservation actions (e.g., Davis and Pinto 2021), including impacts on local SGCN populations. Synthesize existing information (e.g., Jain et al. 2021) and apply modeling techniques to aid in evaluating success when appropriate (e.g., Parks et al. 2018). Adjust future conservation actions as needed based on observed outcomes. Potential collaborators: BLM, BOR, NPS, USACE, USFS, USFWS, USGS, NMED, SFD, SLO, universities.

Biological Resource Use
Inform natural-resource law enforcement staff of the distribution, life history, and habitat needs of SGCN. Partner with them to enforce laws to protect SGCN populations and habitats. Potential collaborators: BLM, NPS, USFS, USFWS.

Biological Resource Use
Support programs that educate the public about the importance of not illegally collecting or harassing SGCN, especially reptiles and amphibians (Pierce et al 2016). Potential collaborators: BLM, DOD, NPS, USFS, USFWS, SLO.

Pollution
Where appropriate, develop green infrastructure and nature-based solutions (Warnell et al. 2023) in urban areas that catch and slow stormwater runoff to prevent pollution from entering aquatic ecosystems and promote groundwater recharge. Potential collaborators: NMDOT, local governments, municipalities, private landowners.

Pollution
Work with appropriate agencies that enforce mining and energy development regulations, Best Management Practices, and safeguards to protect water quality and minimize SGCN mortality associated with mining and energy development. Assess impacts to SGCN and their habitats from industrial activities, including mining and energy development. These impacts may include direct mortality; pollution from produced wastewater (including brine and hydraulic injection fluids), transport of extracted or waste products, or acid mine drainage; noise and light pollution from energy development activities, and sediment runoff from roads. Potential collaborators: BLM, USFS, EMNRD, NMED, SLO, energy and mining companies, local governments.

Biological Resource Use
Work with landowners and land-management agencies to use forests, woodlands (including piñon-juniper woodlands), and savannas in a manner that maintains healthy, and returns degraded, vegetation to an improved composition and function for SGCN, while protecting grassland communities surrounding piñon-juniper woodlands from woody plant invasion. Potential collaborators: BLM, DOD, NPS, USFS, SFD, SLO, private landowners.
