(9) After 32 days of feeding, body weight, liver weight and egg production decreased in birds fed lead while kidney weights increased.
(10) Phyla as diverse as insects, birds, and mammals possess distinct HRAS and KRAS sequences, suggesting that these genes are essential to metazoa.
(11) Changes in brain size are compared with observations found in other domesticated birds.
(12) The presence in lamprey kidney of a loop which is similar to Henle's loop in mammals and birds indicates that the development of the system of osmotic concentration conditioned by the formation in the kidney of the medulla and from a sharp increase in renal arterial blood supply.
(13) We simply do whatever nature needs and will work with anyone that wants to help wildlife.” His views might come as a surprise to some of the RSPB’s 1.1 million members, who would have been persuaded by its original pledge “to discourage the wanton destruction of birds”; they would equally have been a surprise to the RSPB’s detractors in the shooting world.
(14) Water restriction of HYD birds for 5 days as adults stimulated tubule hypertrophy but not to the same extent as the chronic regimen and with no evidence for hyperplasia.

(16) 1 After the injection of labelled procaine and lidocaine in mice, the location and concentration of radioactivity was demonstrated by autoradiographical methods.2 An accumulation in some endocrine cells such as the pancreatic islets, the hypophysis, the adrenal medulla and certain cells of the thyroid (probably representing the calcitonin-producing parafollicular cells) was shown.3 After the injection of [(14)C]-procaine in chicks, an accumulation of radioactivity was observed in the ultimobranchial gland (which produces calcitonin in birds), but not in the thyroid.4 Radioactivity was also shown to be strongly concentrated in structures containing melanin, such as the pigment of the eye, skin and hair and in some organs involved in the metabolism and excretion of these drugs.
(17) Respiration frequency increased during exposure to 35 (four birds) and 40 degrees C (six birds) in the normally hydrated quail, while in the dehydrated quail, respiration frequency increased only in three birds during exposure to 35 degrees C, and four birds during exposure to 40 degrees C, the frequencies were lower during dehydration.
(18) A man in New Zealand suggested that they need to rid the country of cats to protect their native birds.
(19) Birds showed evidence of increased tolerance, with age, to phenylpropanolamine but not to monensin.
(20) Again, changes in birds fed CTN + OA for 7 days were similar but milder.
Junco
Definition:
(n.) Any bird of the genus Junco, which includes several species of North American finches; -- called also snowbird, or blue snowbird.
Example Sentences:
(1) The aggressive tendencies of male dark-eyed juncos Junco hyemalis did not differ significantly following deprivation from food for 20 and 60 min.
(2) Dark-eyed Juncos (Junco hyemalis) were maintained on one of three semi-synthetic diets, differing only in their sulphur amino acid content.
(3) Species of the genus Junco are polymorphic for chromosomes 2 and 5.
(4) A male migratory songbird (dark-eyed junco, Junco hyemalis) was used as a model for studies on the influence of testosterone (T) on feeding, and on interactive effects on this behavior between T and the opioid antagonist naloxone hydrochloride (Nal).
(5) Male, dark-eyed juncos, Junco hyemalis, were held in captivity under conditions simulating winter temperature and photoperiod.
