The habitats and resources utilized by these birds throughout their annual cycle continue to be impacted by human activities, such as fragmentation and deforestation. These activities inflate the inherent consequences of migration (e.g., reduced survival, carry-over effects, and health) and contribute to the continued decline of migratory birds. I studied passerine migration across east-central Illinois from 2012 through 2014. During this time, birds were surveyed during spring and fall migratory periods to address two research questions: 1) what habitat characteristics are indicated by different metrics of habitat quality used to evaluate stopovers for migrants? 2) which birds play a larger role in tick dispersal, and how do habitat characteristics influence infestation? Although migrants were using fragmented study sites, I found little evidence to suggest that they were able to increase energy reserves, although I did detect a slight increase in condition among long-distance migrants in response to shrub-fruit abundance. Vegetation cover was positively related to migrant abundance and richness. I found that short-distance migrants experienced greater infestation prevalence than long-distance migrants. Birds that forage in the forest understory (< 10 m) experienced greater infestation prevalence than canopy foraging species. Ixodes spp. infestation prevalence was influenced by patch size and invasive shrub fruit abundance, while H. leporispalustris was unrelated to avian or habitat characteristics. This research indicates that variation in life-history traits among migratory birds may influence the quality and consequences of stopovers during migratory periods.","Submission published under a 24 month embargo labeled 'U of I only', the embargo will last until 2017-08-01","The student, Christine Parker, accepted the attached license on 2015-07-22 at 16:46.","The student, Christine Parker, submitted this Thesis for approval on 2015-07-22 at 16:53.","This Thesis was approved for publication on 2015-07-23 at 09:20.","DSpace SAF Submission Ingestion Package generated from Vireo submission #8618 on 2015-09-29 at 15:00:57","Made available in DSpace on 2015-09-29T20:50:24Z (GMT).
