Deanna Dawson
Deanna is a emeritus with the Eastern Ecological Science Center located at Laurel, MD.
An experienced field ornithologist, her current research uses remote sensing techniques to sample the spatiotemporal distribution of birds, primarily during migration periods. She collaborates in research that analyzes data from weather surveillance radars to map the densities of nocturnal migrants at daytime stopover sites, and uses acoustic data to quantify and model the abundance of migrants aloft. She also works on methods to estimate animal densities from sounds recorded on microphone arrays, applying them to recordings of bird song made across the Patuxent Research Refuge during the nesting season.

Comparison of neotropical migrant landbird populations wintering in tropical forest, isolated forest fragments, and agricultural habitats Comparison of neotropical migrant landbird populations wintering in tropical forest, isolated forest fragments, and agricultural habitats
Neotropical migrant bird populations were sampled at 76 sites in seven countries by using mist nets and point counts during a six-winter study. Populations in major agricultural habitats were compared with those in extensive forest and isolated forest fragments. Certain Neotropical migrants, such as the Northern Parula, American Redstart, and the Black-throated Blue, Magnolia, Black-and...

Winter habitat occurrence patterns of temperate migrant birds in Belize Winter habitat occurrence patterns of temperate migrant birds in Belize
We used mist nets and point counts to sample bird populations in 61 sites in Belize during January-March of 1987-1991. Sites were classified as forest, second growth, woody agricultural crops (citrus, mango, cacao, and cashew), or non-woody agricultural crops (rice and sugar cane). We evaluated patterns of occurrence of wintering temperate migrant bird species in these habitats. Mist net...

Open marsh water management in the mid-Atlantic region: Aerial surveys of waterbird use Open marsh water management in the mid-Atlantic region: Aerial surveys of waterbird use
Nine marsh sites were selected in Maryland, Delaware, and New Jersey to assess the importance of ponds created by Open Marsh Water Management (OMWM) to migratory birds. At eight of the nine sites, OMWM ponds were paired with areas of similar-sized natural ponds. Eleven aerial surveys were conducted, mostly in fall and winter of 1987 and 1988 to compare relative use of ponds and sites by...
