bird neighbors- 第17部分

Before　flying　up　to　a　twig　to　peck　off　the　insects；　the　birds　have　a　pretty　vireo　trick　of　cocking　their　heads　on　one　side　to　investigate　the　quantity　hidden　underneath　the　leaves。　They　seem　less　nervous　and　more　deliberate　than　many　of　their　restless　family。

Most　warblers　go　over　the　Canada　border　to　nest；　but　there　are　many　records　of　the　nests　of　this　species　in　the　Alleghanies　as　far　south　as　Georgia；　in　the　Catskills；　in　Connecticut；　northern　Minnesota　and　Michigan。　Laurel　thickets　and　moist　undergrowth　of　woods　in　the　United　States；　and　more　commonly　pine　woods　in　Canada；　are　the　favorite　nesting　haunts。　A　sharp　zip；　zip；　like　some　midsummer　insect's　noise；　is　the　bird's　call…note；　but　its　love…song；　zee；　zee；　zee；　or　twee；　twea；　twea…e…e；　as　one　authority　writes　it；　is　only　rarely　heard　in　the　migrations。　It　is　a　languid；　drawling　little　strain；　with　an　upward　slide　that　is　easily　drowned　in　the　full　bird　chorus　of　May。

BLUE　AND　BLUISH　BIRDS


THE　BLUEBIRD　（Sialia　sialis）　Thrush　family

Called　also：　BLUE　ROBIN；　＇EASTERN　BLUEBIRD；　AOU　1998＇

Length　　7　inches。　About　an　inch　longer　than　the　English　　　sparrow。　Male　　Upper　parts；　wings；　and　tail　bright　blue；　with　rusty　wash　　　in　autumn。　Throat；　breast；　and　sides　cinnamon…red。　Underneath　　　white。　Female　　Has　duller　blue　feathers；　washed　with　gray；　and　a　paler　　　breast　than　male。　Range　　North　America；　from　Nova　Scotia。　and　Manitoba　to　Gulf　of　　　Mexico。　Southward　in　winter　from　Middle　States　to　Bermuda　and　　　West　Indies。　Migrations　　March。　November。　Summer　resident。　A　few　sometimes　　　remain　throughout　the　winter。

With　the　first　soft；　plaintive　warble　of　the　bluebirds　early　in　March；　the　sugar　camps；　waiting　for　their　signal；　take　on　a　bustling　activity；　the　farmer　looks　to　his　plough；　orders　are　hurried　off　to　the　seedsmen；　a　fever　to　be　out　of　doors　seizes　one：　spring　is　here。　Snowstorms　may　yet　whiten　fields　and　gardens；　high　winds　may　howl　about　the　trees　and　chimneys；　but　the　little　blue　heralds　persistently　proclaim　from　the　orchard　and　garden　that　the　spring　procession　has　begun　to　move。Tru…al…ly；　tru…al…ly；　they　sweetly　assert　to　our　incredulous　ears。

The　bluebird　is　not　always　a　migrant；　except　in　the　more　northern　portions　of　the　country。　Some　representatives　there　are　always　with　us；　but　the　great　majority　winter　south　and　drop　out　of　the　spring　procession　on　its　way　northward；　the　males　a　little　ahead　of　their　mates；　which　show　housewifely　instincts　immediately　after　their　arrival。　A　pair　of　these　rather　undemonstrative　　matter…of…fact　lovers　go　about　looking　for　some　deserted　woodpecker's　hole　in　the　orchard；　peering　into　cavities　in　the　fence…rails；　or　into　the　bird…houses　that；　once　set　up　in　the　　old…fashioned　gardens　for　their　special　benefit；　are　now　appropriated　too　often　by　the　ubiquitous　sparrow。　Wrens　they　can　readily　dispossess　of　an　attractive　tenement；　and　do。　With　a　temper　as　heavenly　as　the　color　of　their　feathers；　the　bluebird's　sense　of　justice　is　not　always　so　adorable。　But　sparrows　unnerve　them　into　cowardice。　The　comparatively　infrequent　nesting　of　the　bluebirds　about　our　homes　at　the　present　time　is　one　of　the　most　deplorable　results　of　unrestricted　sparrow　immigration。　Formerly　they　were　the　commonest　of　bird　neighbors。

Nest…building　is　not　a　favorite　occupation　with　the　bluebirds；　that　are　conspicuously　domestic　none　the　less。　Two；　and　even　three；　broods　in　a　season　fully　occupy　their　time。　As　in　most　cases；　the　mother…bird　does　more　than　her　share　of　the　work。　The　male　looks　with　wondering　admiration　at　the　housewifely　activity；　applauds　her　with　song；　feeds　her　as　she　sits　brooding　over　the　nestful　of　pale　greenish…blue　eggs；　but　his　adoration　of　her　virtues　does　not　lead　him　into　emulation。

　　　　　　　　　　　　　〃Shifting　his　light　load　of　song；　　　　　　　　　　From　post　to　post　along　the　cheerless　fence；〃

Lowell　observed　that　he　carried　his　duties　quite　as　lightly。

When　the　young　birds　first　emerge　from　the　shell　they　are　almost　black；　they　come　into　their　splendid　heritage　of　color　by　degrees；　lest　their　young　heads　might　be　turned。　It　is　only　as　they　spread　their　tiny　wings　for　their　first　flight　from　the　nest　that　we　can　see　a　few　blue　feathers。

With　the　first　cool　days　of　autumn　the　bluebirds　collect　in　flocks；　often　associating　with　orioles　and　kingbirds　in　sheltered；　sunny　places　where　insects　are　still　plentiful。　Their　steady；　undulating　flight　now　becomes　erratic　as　they　take　food　on　the　wing　　a　habit　that　they　may　have　learned　by　association　with　the　kingbirds；　for　they　have　also　adopted　the　habit　of　perching　upon　some　conspicuous　lookout　and　then　suddenly　launching　out　into　the　air　for　a　passing　fly　and　returning　to　their　perch。　Long　after　their　associates　have　gone　southward；　they　linger　like　the　last　leaves　on　the　tree。　It　is　indeed　〃good…bye　to　summer〃　when　the　bluebirds　withdraw　their　touch　of　brightness　from　the　dreary　November　landscape。

The　bluebirds　from　Canada　and　the　northern　portions　of　New　England　and　New　York　migrate　into　Virginia　and　the　Carolinas；　the　birds　from　the　Middle　States　move　down　into　the　Gulf　States　to　pass　the　winter。　It　was　there　that　countless　numbers　were　cut　off　by　the　severe　winter　of　1894…95；　which　was　so　severe　in　that　section。
