stress and immune responses of nestling tree swallows (tachycineta bicolor) and eastern bluebirds (sialia sialis) exposed to nonpersistent pesticides and p,p'-dichlorodiphenyldichloroethylene in apple orchards of southern ontario, canada.	to determine the relative effects of pesticides in current use and persistent residues of p,p'-dichlorodiphenyldichloroethylene (p,p'-dde), we examined endocrine and immune responses in tree swallow (tachycineta bicolor) and eastern bluebird (sialia sialis) chicks from pesticide-sprayed apple orchards and reference sites in southern ontario, canada, during 2000 to 2001. nests were exposed to as many as seven individual pesticide applications and up to five mixtures of pesticides during the egg-i ...	2004	15648768
thyroid function in nestling tree swallows and eastern bluebirds exposed to non-persistent pesticides and p, p'-dde in apple orchards of southern ontario, canada.	this study examined the associated effects of pesticides and persistent residues of p,p'-dde on thyroid function in 16-day-old tree swallows (tachycineta bicolor) and 12-day-old eastern bluebirds (sialia sialis). apple orchards sprayed with pesticides in current use and reference sites were chosen for study in southern ontario, canada, during 2000-2001. we assessed thyroid hormone concentrations (plasma and muscle thyroxine [t4], and triiodothyronine [t3]) and the response to a challenge with th ...	2005	15943111
