What's the difference between bird and roost?

Bird


Definition:

  • (n.) Orig., a chicken; the young of a fowl; a young eaglet; a nestling; and hence, a feathered flying animal (see 2).
  • (n.) A warm-blooded, feathered vertebrate provided with wings. See Aves.
  • (n.) Specifically, among sportsmen, a game bird.
  • (n.) Fig.: A girl; a maiden.
  • (v. i.) To catch or shoot birds.
  • (v. i.) Hence: To seek for game or plunder; to thieve.

Example Sentences:

  • (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.
