                          Landbird Conservation Plan gives population estimate of 250,000 in the U.S.

                          and Canada (see Rich et al. 2004 for accuracy and precision ratings).

    S-Trend         Decreasing

    S-Trend         Species has declined substantially in the past 35 years.  The atlas survey

    Comment      yielded only one probable record in priority blocks surveyed (Palmer-Ball

                          1996).

    Habitat /        The species is a habitat specialist (NatureServe 2004).  In Kentucky, it is a

    Life History  breeding bird that formerly inhabited a variety of early successional habitats,

                          including old fields and pastures, young pine plantations, and regenerating clear-

                          cuts (Palmer-Ball 1996).  Mengel (1965) described the species as having rather

                          rigid habitat requirements, inhabiting an area only if it possessed the right

                          combination of conditions: preferably (but not always) a hillside, some bare

                          ground, some native grasses and forbs, patches of blackberry briars, and

                          scattered small trees.  Although the presence of pines was not essential, red

                          cedars and other evergreens were frequently associated with such habitats.  In

                          the young pine plantations where the species was once found, the trees ranged

                          from 1 to 10 feet in height, and ground cover included a mixture of grasses,

                          forbs, and patches of bare ground.  NatureServe (2004) describes the species as

                          requiring a well-developed grass and herb layer with limited shrub and

                          hardwood midstory components.  The species is able to colonize recent

                          clearcuts and early seral stages of old field succession but such habitat remains

                          suitable only for a short time.

    Key               Habitat condition is POOR overall in Kentucky.

                          Key Habitat Locations (and their condition):

                          1. Only known current nesting population is on Fort Campbell Military

    Habitat /        This is a resident bird that inhabits a variety of semi-open and open habitats. 

    Life History  Mengel (1965) considered them to be most frequently found in farm country,

                          and it is likely that rural farmland continues to harbor a persistent breeding

                          population.  Today these owls are also reported regularly from older residential

                          areas of cities and towns, where large shade trees provide nest sites.  Small

                          numbers are also reported occasionally from larger cities (Palmer-Ball 1996) and

                           recently young birds have been documented from grain silos.  The species

                          requires large tree cavities and old structures for nesting.

    Key               Habitat condition throughout Kentucky is UNKNOWN for this species.

    Habitat         

                          No key habitat to identify; the species will use appropriate habitat range wide.

    G-Trend        Decreasing

    G-Trend        North American Breeding Bird Survey data reveal that the species has been

    Comment      declining in parts of the U.S. for some time.  Populations in the central and

                          eastern parts of the range are smaller than they were in the past.  Eight states

                          (Wisconsin, Michigan, Ohio, Pennsylvania, West Virginia, Virginia, North

                          Carolina, and South Carolina) reported declines between the 1950s and the

                          1980s from rare or local breeders (or "common" in the case of North Carolina)

                          to near or certain extirpation.  During the period of 1965 to 1979 severe declines

                           occurred in Eastern and Central regions while the West was stable.  In the

                          1980's the decline in the central states subsided, while the population in the

                          eastern states continued to decline to the point that Breeding Bird Survey data

                          was no longer reliable for use in trend analysis (NatureServe 2004).  Partners in

                          Flight North American Landbird Conservation Plan gives Global population

                          estimate of 6,000,000 (see Rich et al. 2004 for accuracy and precision ratings).

    S-Trend         Decreasing

    S-Trend         North American Breeding Bird Survey data for the period 1966-2003 show

    Comment      declines of 9.1% per year (Sauer et al. 2004).  Kentucky Breeding Bird Atlas

                          resulted in confirmed nesting in 7 priority blocks (Palmer-Ball 1996).  Partners

                          in Flight estimates a population of 1,800 individuals (see Rosenberg 2004 for

                          assumptions); however, recent studies documented only one breeding pair and a

                           few unpaired males in the state (Ritchison and Hodge 2003).

    Habitat /        Although this species can occur year round, recent observations are limited to

    Life History  the breeding season.  Bewick's Wrens are encountered in a variety of semi-open

                          habitats.  Although evidence suggests that the species formerly inhabited

                          natural forest openings, it is primarily a bird of altered habitats today.  These

                          wrens are most conspicuous in rural farmland and settlement, but small

                          numbers also inhabit suburban yards of towns, brushy forest margins, and

                          forest clear-cuts (Palmer-Ball 1996).  The most recent nesting record came from

                          a pair utilizing a grill in Scott County (Ritchison and Hodge 2003).  Although

                          suitable habitat seems to persist, it is unknown why the species continues to

                          decline.  The Appalachian subspecies has most likely been extirpated from the

                          state.

    Life History  mature woodlands.  During the breeding season, Brown Creepers occupy

                          permanently inundated swamp forest dominated by bald cypress and water

                          tupelo where it builds nests under exfoliating bark, especially of dead trees. 

                          Although originally thought to be restricted to permanently inundated swamp

                          forests, birds found in Henderson and Union counties were in seasonally

                          inundated bottomland forest and the margins of open water sloughs.  These

                          observations indicate that breeding creepers may be more widespread than

                          formerly believed (Palmer-Ball 1996).

    Key               Habitat condition is FAIR (breeding and wintering) overall in Kentucky.

                          Key Habitat Locations (and their condition):

                          1. Cypress Creek Swamp in Marshall County (fair)

                          2. Sloughs Wildlife Management Area in Henderson County (good)

                          3. Axe Lake Swamp in Ballard County (good)
