Cliff Swallow - Petrochelidon pyrrhonota
FWP Conservation Tier
Separated in all plumages and ages from all other North American swallows except Cave Swallow by a square tail and orange rump. In all populations, exhibits a chestnut-colored throat. Most subspecies show a cream- or white-colored, triangular-shaped forehead patch, characters that separate the species from Cave Swallow. Head and neck are noticeably thicker than other North American swallows (Brown and Brown 1995).

In the Bozeman area, normal migration periods are May 5 to June 1 and August 25 to September 10.
Historically inhabited open canyons, foothills, escarpments, and river valleys that offered a vertical cliff face with a horizontal overhang for nest attachment. Now found in a wide variety of habitats because of use of artificial nesting structures such as bridges and buildings. Avoids heavy forest, desert and alpine areas. Most colony sites are located near open fields or pastures where the birds forage and a water source is often nearby. Proximity to mud source is often cited as a breeding-habitat requirement (Brown and Brown 1995).
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 (high, medium, or low) of each of the 82 ecological systems mapped in Montana for
vertebrate animal species that regularly breed, overwinter, or migrate through the state by:
- 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 2001, Adams 2003, and Werner et al. 2004);
- Evaluating structural characteristics and distribution of each ecological system relative to the species’ range and habitat requirements;
- Examining the observation records for each species in the state-wide point database associated with each ecological system;
- 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 associated as using 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 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.
High, medium, and low habitat quality was assigned based on the degree to which the structural characteristics of an ecological system matched the preferred structural habitat characteristics for each species in the 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 assignments of habitat quality.

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: http://mtnhp.org/requests/default.asp
) 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.

Flying insects at all times of the year. Insects taken reflect local availability. Occasional pieces of seeds are found in stomachs but these represent either accidental ingestion or use as grit (Brown and Brown 1995).
Typically nest in large colonies; a single site may contain up to 3,500 active nests. Nests are made of mud on vertical substrates. Cliff swallows are distinguished by their enclosed, gourd-shaped nests and the larger colonies. Single brood. Clutch size ranges 1 to 6 eggs. Eggs are ground color white, creamy white or pinkish white. Ovate to elliptical-ovate in shape (Brown and Brown 1995). Egg dates near Fortine are from June 9 to July 17. Statewide, nesting occurs from mid-May to mid-July.
