What's the difference between bird and flycatcher?
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:

(7) The enterococcal population of the 'dosed' birds contained a greater proportion of Enterococcus faecium than did that of the control birds while the converse was true for Ent.
(8) Somewhat surprisingly then, in view of the mechanisms in mammals, birds do not seem to use this seasonal message in the photoperiodic control of reproduction.
(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.
(15) Thus, the possibility exists that androgen secretion in some chelonian systems may exhibit a high degree of LH specificity like that of mammals and birds.
(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.
Flycatcher
Definition:
(n.) One of numerous species of birds that feed upon insects, which they take on the wing.
Example Sentences:
(1) It’s home to a quarter of a million people, about 150 elephants and a host of other wild animals ranging from bears and tigers to flycatchers and martens.
(2) A field experiment was performed implanting female pied flycatchers (Ficedula hypoleuca) during the nest-building period with silastic tubes containing 17 beta-estradiol.
(3) Other migrants that spend winter in Africa, such as cuckoos, whinchats and spotted flycatchers, are being found in the UK at half the number they were two decades ago.
(4) Pseudadelphoscolex eburnensis, a new genus and species of metadilepidid Cyclophyllidea parasitic in the red-bellied paradise flycatcher, Terpsiphone rufiventer, from the Ivory Coast, is described.
(5) On his final day, he visited the island of Camino off the Maltese coast and saw more birds than he had all week – spotted flycatchers, hoopoes and golden oriole.
(6) In collared flycatchers (Ficedula albicollis), in contrast, rhythmicity continues under much longer photoperiods, consistent with the fact that the wintering area of this species extends to latitudes far south of the equator.
(7) This idea is further supported by findings in the pied flycatcher (Ficedula hypoleuca), in which a circannual rhythmicity persists only if photoperiod in winter is at least as short as that normally encountered by the species in its wintering grounds slightly north of the equator.
(8) The brains of the swift Streptoprocne zonaris, the flycatcher Tyrannus melancholicus, the tanager Ramphocelus dimidiatus and the finch Oryzoborus angolensis were compared with respect to the hyperstriatum accessorium, hyperstriatum dorsale, hyperstriatum ventrale, neostriatum, ectostriatum, paleostriatum augmentatum and paleostriatum primitivum.
(9) This experiment explored the stimulatory effect of brooding newly hatched young on plasma prolactin concentration in male and female pied flycatchers, Ficedula hypoleuca.
(10) A surprisingly high proportion (42%) of breeding pied flycatchers failed to mob a stuffed pygmy owl placed near the nests.
(11) In the pied flycatcher there exists an anomaly in the relationship between cortical histology and plasma levels of corticosterone during the breeding period.
(12) The pied flycatcher is a polygamous and polyterritorial bird species.
(13) The thresholds of the generation of EP in the L field of two to nine day old pied flycatcher nestlings in response to monotonal bursts of varied frequency were investigated.
(14) Thresholds of field L auditory evoked potentials EP were studied in 1.5-9-day-old nestlings of pied flycatcher in response to pure tone signals of different frequencies.
(15) In an attempt to study this anomaly, binding capacity and binding affinity of plasma corticosterone-binding proteins (CBP) were studied in free-living pied flycatchers during the early and late parts of the breeding period.
(16) Acute ethanol influence on field L auditory evoked potentials (AEP) was studied in 4-8-days-old altricial nestlings of pied flycatcher.
(17) Female flycatchers given 3-day-old nestlings on the day their own eggs hatched showed an earlier reduction in night-time brooding and an earlier decrease in plasma prolactin than did control birds.
(18) Male pied flycatchers Ficedula hypoleuca given injections of long-acting testosterone, when in full breeding condition, maintained spermatogenesis.
(19) Thus, the results show that an elevation of plasma levels of corticosterone in adult pied flycatchers during the nestling period affects parental as well as territorial behavior.
