Bulletin of the Tall Timbers Research Station 8: 1–104. Calderon–Franco, D. 2006. NatureServe, Arlington, Virginia. The Minister of the Environment and the Minister responsible for the Parks Canada Agency is the competent minister for the management of the Cerulean Warbler and has prepared this plan, as per section 65 of SARA. Ontario Partners in Flight. However, for species at risk, as well as other more common species, that inhabit deciduous forests (Table 3), it is likely that increased forest conservation will have beneficial effects. But I managed a few poor record photos before it and its presumed mate flew off into the canopy. 2008. It is among the very The Canadian range for the species is concentrated mainly in two geographic breeding clusters in Ontario; i) in Carolinian forests between lower Lake Huron and Lake Ontario, and ii) in a band extending east from southeastern Georgian Bay toward a relatively dense concentration at the Frontenac Axis near the eastern end of Lake Ontario. 2009). Global range of the Cerulean Warbler (Modified from Ridgely et al. In Quebec, a 1980s ice storm damaged habitat at a site where Cerulean Warblers were regularly observed in the 1960s and 1970s. Bannon, P and M. Robert. They are usually considered to be area–sensitive (COSEWIC 2003). Cerulean Warblers appear to have an entirely insectivorous diet during the breeding season, but will also consume nectar resources during the non–breeding season in South America (COSEWIC 2003). While the cerulean warbler's status may be particularly (i) _____ , it is just one of the many species of migrant birds whose numbers have been (ii) _____ for years. Likewise, thunderstorms can similarly modify habitat to make it unsuitable for Cerulean Warblers. Jones, J., J.J. Barg, T.S. Wintering habitat includes humid evergreen forests on the slopes of the Andes (COSEWIC 2003), although recent studies suggest a high use of modified forests such as shaded coffee and cardamom plantations (Calderon–Franco 2006, Bakermans et al.

This management plan was prepared by John Brett of Environment Canada, Canadian Wildlife Service – Ontario, based on a draft prepared by Talena Kraus of Artemis Eco–Works. Ontario Ministry of Natural Resources.

Its range is somewhat patchy and not contiguous throughout the areas occupied, and there have been casual sightings outside the breeding range (COSEWIC 2003). The Cerulean Warbler is sensitive to habitat changes and modifications. 1141 Route de l'Église, Québec, G1V 4H5. Mature forest habitat has been and continues to be destroyed to accommodate residential, agricultural and other development, and has been described as the most serious long–term threat to the Cerulean Warbler in its breeding range (Hamel 2000). Populations in eastern Ontario had been considered relatively stable (COSEWIC 2003), although more recent studies suggest that an eastern Ontario population may not be producing enough young to counter mortality and support a viable population (Jones et al. Vulnerable – Vulnerable in the jurisdiction due to a very restricted range, relatively few populations (often 80 or fewer), recent and widespread declines, or other factors making it vulnerable to extirpation. Karl Egressy kindly provided the cover photograph. Zoologist, Natural Heritage Information Centre, Biodiversity Section, Fish & Wildlife Branch, Ontario Ministry of Natural Resources, 300 Water St, 2nd Floor North Tower, P.O. My alarm went off at 4:20 AM. They remained off my life list, joining the Yellow-throated Spadebill from earlier. As the small Canadian population of Cerulean Warbler occurs at the northern part of its continental range, and the vast majority of its continental breeding distribution and population occurs further south in the United States, it is important to note that population changes at the continental level may have a significant effect on management of this species in Canada. The federal, provincial, and territorial government signatories under the Accord for the Protection of Species at Risk (1996) agreed to establish complementary legislation and programs that provide for effective protection of species at risk throughout Canada. 2010. Quite a few other Colombian endemic species occur here (Mountain Grackle, Indigo-capped Hummingbird, Colombian Chachalaca, Black Inca, Turqouise Dacnis, Parker's Antbird, etc) but I had seen these previously.

Cadman, M.D, D.A. Version 7.0. 2008. The huge guan noticed me rather quickly and flew up into the trees where it joined a second individual. 1987. Girvan, J.J. Barg, T.K. development). The Cerulean warbler biologist covers the western part of the state’s coalfields and that region. Habitat degradation in its breeding, migrating and wintering ranges over the last decades are suspected of having caused a decline of 72% since the 1970s. Other commonly–used song–post trees identified in this study include sugar maple (Acer saccharum), white ash (Fraxinus americana), and oaks (Quercus spp.). The adult male is deep blue above and white below with a blue–black band across the throat, whereas the adult female is blue–green above and whitish below with a yellow–white eyebrow (COSEWIC 2003). Cerulean Warblers also exhibit habitat selection at smaller scales, and use some portions of their territories (core areas) more than others (COSEWIC 2003, Barg et al. The Birds of North America Online. D.A. Globally, the Cerulean Warbler breeds in eastern North America in the northeastern United States and parts of southeastern Canada (Figure 1). 2008). It is recognized that management of habitat for the benefit of Cerulean Warbler populations could potentially have adverse effects on other species with differing habitat preferences (e.g.
