bird neighbors- 第42部分

This　largest　of　the　warblers　might　be　mistaken　for　a　dozen　birds　collectively　in　as　many　minutes；　but　when　it　is　known　that　the　jumble　of　whistles；　parts　of　songs；　chuckles；　clucks；　barks；　quacks；　whines；　and　wails　proceed　from　a　single　throat；　the　yellow…breasted　chat　becomes　a　marked　specimen　forthwith　　a　conspicuous　individual　never　to　be　confused　with　any　other　member　of　the　feathered　tribe。　It　is　indeed　absolutely　unique。　The　catbird　and　the　mocking…bird　are　rare　mimics；　but　while　the　chat　is　not　their　equal　in　this　respect；　it　has　a　large　repertoire　of　weird；　uncanny　cries　all　its　own　　a　power　of　throwing　its　voice；　like　a　human　ventriloquist；　into　unexpected　corners　of　the　thicket　or　meadow。　In　addition　to　its　extraordinary　vocal　feats；　it　can　turn　somersaults　and　do　other　clown…like　stunts　as　well　as　any　variety　actor　on　the　Bowery　stage。

Only　by　creeping　cautiously　towards　the　roadside　tangle；　where　this　〃rollicking　polyglot〃　is　entertaining　himself　and　his　mate；　brooding　over　her　speckled　eggs　in　a　bulky　nest　set　in　a　most　inaccessible　briery　part　of　the　thicket；　can　you　hope　to　hear　him　rattle　through　his　variety　performance。　Walk　boldly　or　noisily　past　his　retreat；　and　there　is　〃silence　there　and　nothing　more。〃　But　two　very　bright　eyes　peer　out　at　you　through　the　undergrowth；　where　the　trim；　elegant…looking　bird　watches　you　with　quizzical　suspicion　until　you　quietly　seat　yourself　assume　silent　indifference。　〃Whew；　whew！〃　he　begins；　and　then　immediately；　with　evident　intent　to　amuse；　he　rattles　off　an　indescribable；　eccentric　medley　until　your　ears　are　tired　listening。　With　bill　uplifted；　tail　drooping；　wings　fluttering　at　his　side；　he　cuts　an　absurd　figure　enough；　but　not　so　comical　as　when　he　rises　into　the　air；　trailing　his　legs　behind　him　stork…fashion。　This　surely　is　the　clown　among　birds。　But　any　though　he　is；　he　is　as　capable　of　devotion　to　his　Columbine　as　Punchinello；　and　remains　faithfully　mated　year　after　year。　However　much　of　a　tease　and　a　deceiver　he　may　be　to　the　passer…by　along　the　roadside；　in　the　privacy　of　the　domestic　circle　he　shows　truly　lovable　traits。

He　has　the　habit　of　singing　in　his　unmusical　way　on　moonlight　nights。　Probably　his　ventriloquial　powers　are　cultivated　not　for　popular　entertainment；　but　to　lure　intruders　away　from　his　nest。

No　foliage　is　dense　enough　to　hide；　and　no　autumnal　tint　too　brilliant　to　outshine　this　luminous　little　bird　that　in　May；　as　it　migrates　northward　to　its　nesting　ground；　darts　in　and　out　of　the　leafy　shadows　like　a　tongue　of　fire。
