Hitchcock's birds, or the increased rate of exposure to histoplasma from blackbird roost sites.
A statewide survey of populations in proximity to blackbird roost sites to determine exposure to histoplasmosis from such sites has demonstrated that a site harboring Histoplasma capsulatum, even though undisturbed, adds significantly to the exposure rate of proximal populations. Disturbance of such a site increases the exposure rate dramatically with or without concurrent clinical cases of histoplasmosis.
