  • Details on Status Ranking and Review
    Red-eyed Vireo (Vireo olivaceus) Conservation Status Review
    Review Date = 01/15/2009
    Population Size

    ScoreU - Unknown

    CommentUnknown.

    Range Extent

    ScoreG - 200,000-2,500,000 km squared (about 80,000-1,000,000 square miles)

    Comment380525 square kilometers based on Natural Heritage Program range maps

    Area of Occupancy

    ScoreG - 2,000-20,000 km squared (500,000-5,000,000 acres)

    Comment5908 square kilometers based on GAP predicted model.

    Long-term Trend

    ScoreE - Relatively Stable (±25% change)

    CommentRiparian deciduous and mixed deciduous forests relatively stable since European arrival.

    Short-term Trend

    ScoreE - Stable. Population, range, area occupied, and/or number or condition of occurrences unchanged or remaining within ±10% fluctuation

    CommentBreeding Bird Survey (BBS) has moderate credibility in Montana and shows an increase of 0.5% per year since 1980 which is a 5 percent increase over a 10 year time period.

    Threats

    ScoreF - Widespread, low-severity threat. Threat is of low severity but affects (or would affect) most or a significant portion of the population or area.

    CommentLoss of regeneration of cottonwood forests due to altered hydrology and grazing. Cowbirds.

    SeverityLow - Low but nontrivial reduction of species population or reversible degradation or reduction of habitat in area affected, with recovery expected in 10-50 years.

    CommentHabitat would likely recover in 10-50 years if hydrology and grazing impacts reduced

    ScopeHigh - > 60% of total population or area affected

    CommentA high percentage of deciduous riparian bottomlands are being impacted.

    ImmediacyModerate - Threat is likely to be operational within 2-5 years.

    CommentOngoing but could accelerate

    Intrinsic Vulnerability

    ScoreC - Not Intrinsically Vulnerable. Species matures quickly, reproduces frequently, and/or has high fecundity such that populations recover quickly (< 5 years or 2 generations) from decreases in abundance; or species has high dispersal capability such that extirpated populations soon become reestablished through natural recolonization (unaided by humans).

    Environmental Specificity

    ScoreB - Narrow. Specialist. Specific habitat(s) or other abiotic and/or biotic factors (see above) are used or required by the Element, but these key requirements are common and within the generalized range of the species within the area of interest.

    CommentRiparian deciduous forest specialist

 
General Description
A 15-cm-long bird with a sturdy, slightly hooked bill, blue-gray crown, white eyebrow (bordered above and below with black), dark olive back, darker wings and tail, pale, unstreaked underparts, and a red eye (brown in fall juveniles); immatures and some fall adults are yellow on the flanks and undertail coverts; subspecies flavoviridis, which sometimes occurs in California and Texas, is yellower overall, with less distinct black lines on the head.

Migration
In the Bozeman area, normal migration periods are May 23 to June 10 and August 20 to September 10.

Habitat
More often heard than seen. Range wide, breeds in deciduous and mixed deciduous-coniferous forest. Absent from sites where understory shrubs are sparse or lacking. Often found near small openings in forest canopy. Can occur in residential areas, city parks, and cemeteries where large trees grow. During spring and fall migration uses a greater variety of forested habitats than during breeding season, but still prefers deciduous woodland over conifers. Winter range finds them present in various forested habitats from sea level up to 3000 m elevation (Cimprich et al. 2000).

Ecological Systems Associated with this Species
  • Details on Creation and Suggested Uses and Limitations
    How Associations Were Made
    We associated the use and habitat quality (common or occasional) of each of the 82 ecological systems mapped in Montana for vertebrate animal species that regularly breed, overwinter, or migrate through the state by:
    1. Using personal observations and reviewing literature that summarize the breeding, overwintering, or migratory habitat requirements of each species (Dobkin 1992, Hart et al. 1998, Hutto and Young 1999, Maxell 2000, Foresman 2012, Adams 2003, and Werner et al. 2004);
    2. Evaluating structural characteristics and distribution of each ecological system relative to the species' range and habitat requirements;
    3. Examining the observation records for each species in the state-wide point observation database associated with each ecological system;
    4. Calculating the percentage of observations associated with each ecological system relative to the percent of Montana covered by each ecological system to get a measure of "observations versus availability of habitat".
    Species that breed in Montana were only evaluated for breeding habitat use, species that only overwinter in Montana were only evaluated for overwintering habitat use, and species that only migrate through Montana were only evaluated for migratory habitat use.  In general, species were listed as associated with an ecological system if structural characteristics of used habitat documented in the literature were present in the ecological system or large numbers of point observations were associated with the ecological system.  However, species were not listed as associated with an ecological system if there was no support in the literature for use of structural characteristics in an ecological system, even if point observations were associated with that system.  Common versus occasional association with an ecological system was assigned based on the degree to which the structural characteristics of an ecological system matched the preferred structural habitat characteristics for each species as represented in scientific literature.  The percentage of observations associated with each ecological system relative to the percent of Montana covered by each ecological system was also used to guide assignment of common versus occasional association.  If you have any questions or comments on species associations with ecological systems, please contact the Montana Natural Heritage Program's Senior Zoologist.

    Suggested Uses and Limitations
    Species associations with ecological systems should be used to generate potential lists of species that may occupy broader landscapes for the purposes of landscape-level planning.  These potential lists of species should not be used in place of documented occurrences of species (this information can be requested at: mtnhp.org/requests) or systematic surveys for species and evaluations of habitat at a local site level by trained biologists.  Users of this information should be aware that the land cover data used to generate species associations is based on imagery from the late 1990s and early 2000s and was only intended to be used at broader landscape scales.  Land cover mapping accuracy is particularly problematic when the systems occur as small patches or where the land cover types have been altered over the past decade.  Thus, particular caution should be used when using the associations in assessments of smaller areas (e.g., evaluations of public land survey sections).  Finally, although a species may be associated with a particular ecological system within its known geographic range, portions of that ecological system may occur outside of the species' known geographic range.

Food Habits
In North America, consumes mostly insects, particularly caterpillars. During breeding season most often observed foraging in canopy vegetation. Also eats various small fruits, most frequently in late summer and fall. In winter, mostly frugivorous (Cimprich et al. 2000).

Reproductive Characteristics
Nest is built in terminal or sub-terminal fork of branch in live midstory to understory tree or shrub, frequently shaded and concealed by vegetation above. Eggs are oval to short oval. They are dull white speckled irregularly and sparsely. Clutch size ranges from 1 to 5 eggs (Cimprich et al. 2000). Near Fortine, egg dates range from June 29 to July 8; most young leave the nest in early July. Statewide, Red-eyed Vireos breed from mid-June through July.
