Michigan is one of and wind turbines, all of which are increasing in these (West Virginia the other), with BBS data number, will continue to pose a threat to Veery for Veery showing an increase since 1966, abundance (Taylor 1972, Shire et al. 2000, though markedly slowing from 1980 to 2007. A Erickson et al. 2001). closer look at BBS data during 1966-1996, using the estimating equations procedure (Link and Sauer 1994), shows the SLP, the tip of the mitt and the eastern UP exhibit a population increases of greater than 1.5% per year while the western UP and the central and western NLP exhibit a decrease of greater than 1.5% per year (Sauer et al. 2008). Reasons for Michigan’s statewide trends in Veery populations as reported by the BBS are not obvious. For the state of Michigan as a whole, there is not a significant population trend during the two atlas periods and intervening years (1983-2007) (Sauer et al 2008). MBBA II data shows a 6% statewide shift downward in detections from MBBA I. The NLP and UP had relatively small changes in detection compared to the SLP which dropped from 52% to 40% of townships. The second Ontario, and the New York breeding bird atlas efforts also found fewer detections in their second project. The Ontario breeding bird atlas showed consistent declines throughout the majority of the survey area (Friesen 2007). Similarly, BBS data for New York during 1966- 2005 demonstrated a 1.5% per year decline in Veery populations (Lowe and Hames 2008). Conservation Needs Like many other forest breeding birds, Veeries are an area sensitive species. Therefore, fragmentation of breeding habitat will continue to pose a threat to population stability (Bevier et al. 2005).

  • Experimental Removal of Strong and Weak Predators: Mice and Chipmunks Preying on Songbird Nests
    Ecology, 82(10), 2001, pp. 2927±2936 q 2001 by the Ecological Society of America EXPERIMENTAL REMOVAL OF STRONG AND WEAK PREDATORS: MICE AND CHIPMUNKS PREYING ON SONGBIRD NESTS K. A. SCHMIDT,1 J. R. GOHEEN,2 R. NAUMANN,R.S.OSTFELD,E.M.SCHAUBER, AND ALAN BERKOWITZ Institute of Ecosystem Studies, Box AB, Millbrook, New York 12545 USA Abstract. We examined the effects of separate removal experiments of two generalist consumers, the white-footed mouse (Peromyscus leucopus) and the eastern chipmunk (Tam- ias striatus), on nest predation rates of forest songbirds. Mice are numerically dominant at our study sites and were shown to be strong predators in other predator±prey interactions, such as those involving gypsy moths. Therefore, we hypothesized that removal of mice would result in decreased levels of nest predation relative to control treatments with a complete predator assemblage, but that the removal of chipmunks would not result in decreased nest predation. Both hypotheses were supported. Mice depredated .60% of arti®cial nests in control plots (mouse populations intact), whereas chipmunks depredated ;20%. Daily nest mortality rates in mouse removal treatments were less than half the rates in controls but were virtually identical between chipmunk removal and control treatments. Nonetheless, when we examined predation rates across plots in which the density of mice varied naturally, total daily mortality rates declined as the density of mice increased. This pattern occurred because mortality from non-mouse predators decreased as the density of mice increased and overwhelmed increasing mortality from mice to drive the overall dy- namics of the system.

  • Veery (Catharus Fuscescens)
    Veery (Catharus fuscescens) NMPIF level: Biodiversity Conservation Concern, Level 1 (BC1) NMPIF assessment score: 12 NM stewardship responsibility: Low National PIF status: No special status New Mexico BCRs: 16 Primary breeding habitat(s): Montane Riparian Summary of Concern Veery is a widespread neotropical migrant with a mostly northern breeding distribution. A small number breed regularly in dense montane riparian habitat at one or two locations in northern New Mexico. This state breeding restriction makes this species highly vulnerable in New Mexico. Associated Species Yellow Warbler, Black-headed Grosbeak, Lazuli Bunting (BC2), Song Sparrow Distribution Veeries breed in a wide band across the northern United States and southern Canada, extending further south along the mountain chains of the eastern United States and the Rocky Mountains. This species is a long-distant neotropical migrant, wintering primarily in south-central and southeast Brazil (Remsen 2001, Bevier et al. 2004). At the southern limit of their breeding range in northern New Mexico, Veeries occur only along the Rio Pueblo and tributaries near Penasco in Taos County, and along the Rio Chama in Rio Arriba County (Parmeter et al. 2002). Ecology and Habitat Requirements Across its range, Veery inhabits damp, deciduous forests, favoring the dense understory that is often more characteristic of disturbed or early successional habitats. Moisture regime is a chief factor in habitat selection. Heavy shrub cover is critical for this species, which in New Mexico is often associated with streamside alder thickets. Habitat in northern New Mexico consists of dense montane riparian vegetation alongside streams, particularly along wider valley floors. Narrow canyons are avoided.

  • Veery CONSERVATION PRIORITY in IOWA Catharus Fuscescens
    IOWA AUDUBON IOWA IBA EDUCATION INITIATIVE PART 4: SPECIES ACCOUNTS STATUS: HIGH Veery CONSERVATION PRIORITY IN IOWA Catharus fuscescens Introduction A shy, tawny colored thrush with a beautiful song that cascades through the deep woods on its breeding grounds in the U.S. and Canada, the Veery was once a familiar sound in parts of Iowa. But the species is apparently disappearing from many of the habitats where it was once more numerous. This Neotropical migrant crosses the Gulf of Mexico in spring and fall, and breeds in damp, early-succession, deciduous forests, often near streamside thickets or swamps. The Veery's distinctive song prevails at dusk, and this species can distinguish between the vocalizations of neighbors and strangers, reacting aggressively when the latter intrude on a territory.
