The brown-headed cowbird and its riparian-dependent hosts in New Mexico

Publications Posted on: August 01, 2018
Numbers of brown-headed cowbirds ( Molothrus ater) are increasing in some regions of North America, while certain populations of long-distance, neotropical migratory songbirds (NTMs) are declining. In the Southwestern United States, several species of NTMs nest only in riparian habitats.

Status, ecology, and conservation of the southwestern willow flycatcher

Publications Posted on: May 12, 2016
This publication was prepared in response to a need expressed by southwestern agencies and organizations for a comprehensive assessment of the population status, history, biology, ecology, habitats, threats, and conservation of the southwestern willow flycatcher (Empidonax traillii extimus). The southwestern willow flycatcher was federally listed as an Endangered subspecies in 1995.

Riparian species reports

Documents and Media Posted on: February 11, 2016
Resource managers need tools that identify the likely future of riparian habitats under various climate and fire scenarios. These tools can help focus limited resources on the most critical needs for wildlife species and identify opportunities for promoting natural regeneration of riparian woodland and wetland habitats. These species vulnerability pamphlets summarize potential effects of fire and climate change on native and nonnative species residing within New Mexico riparian, wetland and associated upland habitats.

Implications of climate change for bird conservation in the southwestern U.S

Publications Posted on: January 12, 2016
Future expected changes in climate and human activity threaten many riparian habitats, particularly in the southwestern U.S. Using Maximum Entropy (MaxEnt3.3.3) modeling, we characterized habitat relationships and generated spatial predictions of habitat suitability for the Lucy’s warbler (Oreothlypis luciae), the Southwestern willow flycatcher (Empidonax traillii extimus) and the Western yellow-billed cuckoo (Coccyzus americanus).

Microhabitat use by breeding Southwestern Willow Flycatchers on the Gila River, New Mexico

Publications Posted on: April 13, 2011
The endangered Southwestern Willow Flycatcher (Empidonax traillii extimus) breeds at numerous sites throughout its range that vary greatly in floristics, vegetation structure, and the extent of human alteration of the habitat. Here we present information on nesting habitat characteristics of Willow Flycatchers in the largest extant population of the subspecies along the upper Gila River in New Mexico.

Unusual nest sites for southwestern Willow Flycatchers

Publications Posted on: August 18, 2010
The endangered southwestern Willow Flycatcher (Empidonax traillii extimus) is an obligate riparian species that typically nests in willow (Salix spp.) thickets or other dense, shrubby habitats. We report on the first nests in Arizona sycamore (Platanus wrightii) and in a climbing rose vine (Rosa multiflora).

Final recovery plan of the southwestern willow flycatcher (Empidonax traillii extimus)

Publications Posted on: July 19, 2010
The Southwestern Willow Flycatcher Recovery Team is composed of a Technical Subgroup (pg. ii), six Implementation Subgroups (Appendix A), and a Tribal Working Group.

Recovering southwestern willow flycatcher populations will benefit riparian health

Publications Posted on: July 19, 2010
When the U.S. Fish and Wildlife Service (USFWS) listed the southwestern willow flycatcher (Empidonax traillii exigua) as federally endangered in 1995, new incentives, controversies and energy were generated to conserve and restore southwestern riparian ecosystems. Close attention has been focused on river and stream conservation in the Southwest since at least 1977, when the U.S.

Chapter 11: Research needs

Publications Posted on: June 16, 2009
Until the southwestern willow flycatcher was proposed for listing as an endangered species in 1993, it was subject to relatively little scientific scrutiny, in part because it is drab, prone to inhabiting dense, wet thickets, and difficult to identify and observe. Consequently, it remained one of the lesser-known of North American birds.

Chapter 10: Management recommendations

Publications Posted on: June 16, 2009
This chapter was developed over a series of meetings using a group-consensus process. Our recommendations are based on published results, on information compiled in the previous chapters, on expert opinion, and on unpublished data of conservation team members. This chapter is available as temporary guidance until the Recovery Plan for the southwestern willow flycatcher is published in the Federal Register.
