Taxonomic Classification Of Viral And Bacterial Dna Following 2021 Avian Mass Mortality Event, Tessa Baillargeon
Honors Theses and Capstones
From May through July 2021, an unusual mortality event occurred along the eastern coast and Midwest of the United States. Thousands of birds, mostly from the order Passeriformes, were part of the die-off including blue jays (Cyanocitta cristata), common grackles (Quiscalus quiscula), European starlings (Sturnus vulgaris), American robins (Turdus migratorius). Clinical signs included crusted eyes, swollen conjunctiva, otitis, seizures, and ataxia.
The New Hampshire Veterinary Diagnostic Laboratory (NHVDL) received over 100 affected birds from various collaborators throughout the United States including Washington DC, NJ, CT, MD, and OH. Given the timing and geologic …

Effects Of Aging On The Reproductive Success Of Female Saltmarsh Sparrows (Ammospiza Caudacutus) In Maine And New Hampshire, Isabella Rose Collamati
Honors Theses and Capstones
The saltmarsh sparrow (Ammospiza caudacutus) is a ground-nesting specialist in coastal salt marshes of the Northeast. Rising sea-levels increase the loss of offspring due to tidal flooding, reducing nest success and resulting in a sharp population decline. In other avian species, age has been shown to affect nest success through altering fertility, behavior, and the number of young produced, favoring older individuals. I investigated age effects on nest success of female saltmarsh sparrows using nest monitoring data collected at four sites of a long-term demographic monitoring project: Chapman's Landing (Stratham, NH), Eldridge Marsh (Wells, ME), Popham Beach (Phippsburg, …
