P\u00e5 verdensbasis er det flere arter som g\u00e5r under betegnelsen kjerrhauker (Circus)<\/em>, bl.a. sivhauk<\/u><\/a>, enghauk<\/u><\/a> og steppehauk<\/u><\/a>.<\/p>\n\n\n\n

St\u00f8rrelse: 43 \u2013 51 cm. (litt mindre enn <\/em>musv\u00e5k<\/u><\/em><\/a> \u2013 litt st\u00f8rre enn <\/em>kr\u00e5ke<\/u><\/em><\/a>)<\/em>. Vingespennet er 105 \u2013 125 cm. Hunnen er st\u00f8rre enn hannen. Vekt: 300-400g (\u2642), 400-700g (\u2640). Hannen er lys bl\u00e5gr\u00e5, vingespissene er svarte.

Utbredelse og bestandsstatus<\/strong><\/p>\n\n\n\n

Myrhauken finnes i Norge<\/u><\/a> p\u00e5 de s\u00f8rlige fjellviddene og i omr\u00e5dene langs grensen mot Sverige<\/u><\/a> fra Tr\u00f8ndelag<\/u><\/a> og nordover til Finnmark<\/u><\/a> samt noen f\u00e5 eksemplarer p\u00e5 J\u00e6ren<\/u><\/a>. I september<\/u><\/a> \u2013 oktober<\/u><\/a> trekker den til midtre- og s\u00f8rlige Europa<\/u><\/a>. Noen eksemplarer overvintrer p\u00e5 J\u00e6ren, i s\u00f8r Sverige og i Danmark<\/u><\/a>. Den returnerer i mars \u2013 april.<\/p>\n\n\n\n

Biotop<\/strong><\/p>\n\n\n\n

Myrhauken er avhengig av myrlendt omr\u00e5de, gjerne omkranset at tett halvh\u00f8y vegetasjon (i Norge vierkjerr)<\/p>\n\n\n\n

Hekking<\/strong><\/p>\n\n\n\n

Myrhauken legger redet p\u00e5 bakken i h\u00f8yt vierkjerr<\/u><\/a>, der den legger 3-6 lys gr\u00f8nne egg i mai<\/u><\/a> \u2013 juni<\/u><\/a>. Rugetiden er 28-31 dager. Redetiden er 6-7 uker.<\/p>\n\n\n\n

F\u00f8de: <\/strong>F\u00f8den er vesentlig sm\u00e5gnagere og sm\u00e5fugl<\/p>\n\n\n\n
