lace；　the　swamp　sparrow　and　the　short…billed　marsh　wren；　but　you　may　know　by　its　long；　slender　bill　that　it　is　not　the　latter；　and　by　the　absence　of　a　bright　bay　crown　that　it　is　not　the　shyest　of　the　sparrows。　

These　marsh　wrens　appear　to　be　especially　partial　to　running　water；　their　homes　are　not　very　far　from　brooks　and　rivers；　preferably　those　that　are　affected　in　their　rise　and　flow　by　the　tides。　They　build　in　colonies；　and　might　be　called　inveterate　singers；　for　no　single　bird　is　often　permitted　to　finish　his　bubbling　song　without　half　the　colony　joining　in　a　chorus。

Still　another　characteristic　of　this　particularly　interesting　bird　is　its　unique　architectural　effects　produced　with　coarse　grasses　woven　into　globular　form　and　suspended　in　the　reeds。　Sometimes　adapting　its　nest　to　the　building　material　at　hand；　it　weaves　it　of　grasses　and　twigs；　and　suspends　it　from　the　limb　of　a　bush　or　tree　overhanging　the　water；　where　it　swings　like　an　oriole's。　The　entrance　to　the　nest　is　invariably　on　the　side。

More　devoted　homebodies　than　these　little　wrens　are　not　among　the　feathered　tribe。　Once　let　the　hand　of　man　desecrate　their　nest；　even　before　the　tiny　speckled　eggs　are　deposited　in　it；　and　off　go　the　birds　to　a　more　inaccessible　place；　where　they　can　enjoy　their　home　unmolested。　Thus　three　or　four　nests　may　be　made　in　a　summer。


SHORT…BILLED　MARSH　WREN　（Cistothorus　stellaris）　Wren　family

＇Called　also：　SEDGE　WREN；　AOU　1998＇

Length　　4　to　5　inches。　Actually　about　one…third　smaller　than　　　the　English　sparrow；　but　apparently　only　half　its　size。　Male　and　Female　　Brown　above；　faintly　streaked　with　white；　　　black；　and　buff。　Wings　and　tail　barred　with　same。　Underneath　　　white；　with　buff　and　rusty　tinges　on　throat　and　breast。　Short　　　bill。　Range　　North　America；　from　Manitoba　southward　in　winter　to　Gulf　　　of　Mexico。　Most　common　in　north　temperate　latitudes。　Migrations　　Early　May。　Late　September。

Where　red…winged　blackbirds　like　to　congregate　in　oozy　pastures　or　near　boggy　woods；　the　little　short…billed　wren　may　more　often　be　heard　than　seen；　for　he　is　more　shy；　if　possible；　than　his　long…billed　cousin；　and　will　dive　down　into　the　sedges　at　your　approach；　very　much　as　a　duck　disappears　under　water。　But　if　you　see　him　at　all；　it　is　usually　while　swaying　to　and　fro　as　he　clings　to　some　tall　stalk　of　grass；　keeping　his　balance　by　the　nervous；　jerky　tail　motions　characteristic　of　all　the　wrens；　and　singing　with　all　his　might。　Oftentimes　his　tail　reaches　backward　almost　to　his　head　in　a　most　exaggerated　wren…fashion。

Samuels　explains　the　peculiar　habit　both　the　long…billed　and　the　short…billed　marsh　wrens　have　of　building　several　nests　in　one　season；　by　the　theory　that　they　are　made　to　protect　the　sitting　female；　for　it　is　noticed　that　the　male　bird　always　lures　a　visitor　to　an　empty　nest；　and　if　this　does　not　satisfy　his　curiosity；　to　another　one；　to　prove　conclusively　that　he　has　no　family　in　prospect。

Wild　rice　is　an　ideal　nesting　place　for　a　colony　of　these　little　marsh　wrens。　The　home　is　made　of　sedge　grasses；　softly　lined　with　the　softer　meadow　grass　or　plant…down；　and　placed　in　a　tussock　of　tall　grass；　or　even　upon　the　ground。　The　entrance　is　on　the　side。　But　while　fond　of　moist　places；　both　for　a　home　and　feeding　ground；　it　will　be　noticed　that　these　wrens　have　no　special　fondness　for　running　water；　so　dear　to　their　long…billed　relatives。　Another　distinction　is　that　the　eggs　of　this　species；　instead　of　being　so　densely　speckled　as　to　look　brown；　are　pure　white。

One　of　the　shatterings　of　childish　impressions　that　age　too　often　brings　is　when　we　learn　by　the　books　that　our　〃merry　brown　thrush〃　is　no　thrush　at　all；　but　a　thrasher　　first　cousin　to　the　wrens；　in　spite　of　his　speckled　breast；　large　size；　and　certain　thrush…like　instincts；　such　as　never　singing　near　the　nest　and　shunning　mankind　in　the　nesting　season；　to　mention　only　two。　Certainly　his　bold；　swinging　flight　and　habit　of　hopping　and　running　over　the　ground　would　seem　to　indicate　that　he　is　not　very　far　removed　from　the　true　thrushes。　But　he　has　one　undeniable　wren…like　trait；　that　of　twitching；　wagging；　and　thrashing　his　long　tail　about　to　help　express　his　emotions。　It　swings　like　a　pendulum　as　he　rests　on　a　branch；　and　thrashes　about　in　a　most　ludicrous　way　as　he　is　feeding　on　the　ground　upon　the　worms；　insects；　and　fruit　that　constitute　his　diet。
