Abstract: The effects of length of caging and reserpine administration on the in vivo recording of uptake and retention of idoine-131 by the thyroid glands of House Sparrows (Passer domesticus) were investigated. The uptake of iodine-131 was lower in birds caged for shorter periods (2 and 10 days) as compared to those caged for longer periods (90 and 100 days) prior to testing. The release of radioiodine from the thyroid area as measured by logarithmically plotted "release slopes" seems depressed in birds held only 2 days prior to testing. Release in birds held for 10 days did not differ appreciably from that in birds held 90 days prior to testing. Uptake and retention of iodine-131 did not differ significantly between birds given reserpine and those given a placebo, either in a group of birds tested 2 days or one tested 90 days after capture.
