Inhabiting the interstitial: design experiments in aviary architecture and habitat creation
… ecological studies, and design prototypes for aviary architecture in downtown Chicago. Bird habitats will be introduced into urban interstices by identifying the unique requirements of habitats and the conditions of interstitial spaces and species.

Behavior, welfare, production and bioenergetics of laying hens in alternative housing systems
… to alternative housing (e.g., enriched colony, aviary cage-free) is increasingly occurring in various parts of the world, especially in Europe and the United States, to meet animal welfare requirements or legislations. This dissertation had the central goal of providing scientific knowledge or …

Radiation in the genus Amazilia: A comparative approach to understanding the diversification of hummingbirds.
… of a polyphyletic origin. Chapter 4 describes an aviary experiment conducted to assess differences in color discrimination and learning abilities among resident and migrant hummingbirds. I found that switching was the most efficient behavioral response to changes in the aviary, but some …

Musical form in non-narrative video
… form-generated pieces are outlined. "Aviary" and "Counterpoint" are video scores which present two different approaches to music image composition. A score system in which video and audio can be synchronized via SMPTE Time Code and MIDI Digital Audio Code is examined. Increasing …

The frequency of scrounging by foraging spice finches affects flock geometry
… as they foraged for hidden clumps of food on an aviary floor. I altered the proportions of scrounging effort in a flock and compared flocks in which I expected low proportions of scrounging to those in which I expected high proportions. As predicted, flocks were significantly more compact when …

Habitat partitioning by sparrows along an elevational gradient
… individuals of each species were placed in an aviary and allowed to forage in each habitat. Observed differences in food intake rate between habitats were small suggesting that species would be more broadly distributed if food shaped their distributions. Predation could be responsible for …

Acorn Caching and Consumption of Weevil-infested Nuts: Possible Means of Tannin Circumvention for the Blue Jay
… status and then offered to individual jays in an aviary setting. Jays handled and consumed non-infested nuts significantly more often than infested nuts, and proportional use of infested nuts did not increase during continued exposure to a high tannin diet. Acorns in simulated caches did not …

Anting Behavior in Birds: Ant Selection and Effect of ant Chemistry on Feather Ectoparasites
… experiments with captive songbirds in an aviary. Experimental results revealed that bird responses to ants included either consumption without anting behavior, anting displays without ant consumption, or consumption of manipulated ants following anting displays. Birds were highly selective …

Alternate Housing for Laying Hens
… incorporate advantages found in battery cage and aviary housing systems. This includes separation from fecal matter, increased horizontal space per bird over commercial battery housing, space for vertical movements, a small group number, perches and nestboxes. A dustbathing area was included in …

Prevalence and Identity of Tissue Cyst Forming Apicomplexan Parasites in the Muscles of Raptors
… species of birds suffering encephalitis in an aviary in California. Hawks (Accipiter species) are believed to be the source of infection. The prevalence of T. gondii was 18.4% (21 of 114) in these birds by PCR, but none were positive by histopathology. N. caninum prevalence in raptors has been …

MOVING THE GOALPOSTS: MIGRATORY BIRDS IN A CHANGING WORLD
… been little studied during migration. Using an aviary experiment, I exposed wild Gray Catbirds Dumetella carolinensis to either a hawk or a domestic cat and observed their behaviors before and after exposure to determine if they responded appropriately to the threat posed by each predator. When …
