DESCRIPTION:When animals experience ambient temperatures outside their the
 rmoneutral zone\, i.e. when they need to actively produce heat or get rid 
 of surplus heat\, a possible adaptation would be to decrease or increase\,
  respectively\, body temperature to reduce the gradient between body tempe
 rature and ambient temperature. \n\nI will give some examples of such adap
 tations in birds during night in winter and foraging during the hot day in
  a tropical environment. During the winter birds decrease and in hot envir
 onments they increase their body temperature\, thus not being strictly hom
 eothermic. Also passerines breeding in temperate areas may face problems t
 o dissipate heat produced as a result of a high metabolic rate when feedin
 g nestlings. \n\nTowards the end I will try to answer the question – “
 Do birds get fever?”. Fever being another possible adaptive reason for a
 ltering the normal body temperature.
