In bottomland forests in Tennessee breeding densities averaged 48 pairs per 40 ha (Petit 1986); in inland wetlands in Illinois densities averaged 24 pairs per 40 ha (Kleen 1973). Most of the smallest ones travel in large mixed flocks for safety. Prothonotary Warbler Minnesota Conservation Summary Audubon Minnesota Spring 2014 The Blueprint for Minnesota Bird Conservation is a project of Audubon Minnesota written by Lee A. Pfannmuller (firstname.lastname@example.org) and funded by the Environment and Natural Resources Trust Fund. Yellow Warblers fly non-stop across the Gulf of Mexico to spend the winter in Central America or northern South America. Version 12.23.2015. Sings a loud, piercing series of 6–10 high-pitched On songbirds that are too small to carry GPS units, scientists use geolocators, mini high-tech backpacks, which weigh much less. The Prothonotary Warbler population has declined 40 percent since the 1960s and the preferred breeding habitats – swamps and forested wetlands – are also disappearing at an alarming rate. Working off-campus? “The Prothonotary Warbler.” Oologist 7: 228–229. Minnesota has designated it a Species in Greatest Conservation Need (Minnesota Department of Natural Resources 2015). They more commonly breed in Missouri, Arkansas and the south but a few do choose to breed in our area. Migratory timing, rate, routes and wintering areas of White-crested Elaenia (Elaenia albiceps chilensis), a key seed disperser for Patagonian forest regeneration. The second and third weeks of May are probably the busiest weeks of the spring for those of us who enjoy birds. Those ancestors liked what they found – longer summer days, an abundance of blossoms and insects and plenty of nesting sites. Petit, Lisa J., and Daniel R. Petit. Hubert, B. Cutright, Noel, Bettie R. Harriman, and Robert W. Howe, eds. All graphics are relative to the Eastern time zone. Laurel, MD: U.S. Geological Survey Patuxent Wildlife Research Center. Please check back later for updates, and make sure you spend some time outside! According to Wikipedia, they winter in the mountains from Colombia to Peru at heights of 2,000-8,000 feet. But I’m using some of last year’s photos when they’re better than some of the ones I took during this year’s cold, rainy spring. Minnesota Ornithologists’ Union Occasional Papers, no 2. Your support helps secure a future for birds at risk. In 1941 there was a report of nesting at another location along the Rum River, in Anoka (Breckenridge 1945), and during the summer of 1945 a well-established breeding population was documented along the St. Croix River, from Stillwater north to Taylors Falls (Hubert 1945). 2006). “Southern Birds in Stearns County.” Loon 36: 104. Spread the word. http://www.partnersinflight.org/wp-content/uploads/2016/08/pif-continental-plan-final-spread-single.pdf. Whitcomb, R. F., Chandler S. Robbins, J. F. Lynch, B. L. Whitcomb, M. K. Klimkiewicz, and D. Bystrak. In Minnesota, such sites are typically within the floodplains of large river systems including the Mississippi, St. Croix, and Minnesota Rivers. The Birds of Minnesota. Taxonomy. Audubon and LABO will continue building and installing nest boxes, training new citizen scientists and building awareness to help monitor Prothonotary Warbler populations. This map depicts the range boundary, defined as the areas where the species is estimated to occur at a rate of 5% or more for at least one week within the post-breeding migration season. Geographic position and landscape composition explain regional patterns of migrating landbird distributions during spring stopover along the northern coast of the Gulf of Mexico. Prothonotary Warblers have high nest site Migratory data gathered from geolocator will be Galadriel’s combined with additional Prothonotary Warbler geolocator recoveries.
