MiGRATiox Kecords FOR Kaxsas Birds 107 



captured by museum on December 11, April 1. April 6, April 26, 

 and in the winter months. They do not arrive till late in the fall. 

 181. Olor b/fcciria^or— Trumpeter Swan. 

 A rare migrant. The only record is for March 23, 



Family IBIDIDAE — Ibises. 



An interesting feature of this group of heron-like birds is that 

 the southern species, which make up the main part of the group, 

 will often wander far north of their breeding range after nesting. 

 187. PJcgadis guarauna — White-faced Glossy Ibis. 



This species rarely wanders over Kansas after breeding season. 



Family ARDEIDAE — Bitterns, Herons, Etc. 



190. Botaurus lentiginosus — Bittern. 



A common summer resident. They were seen daily in 1917 after 

 May 10, though none were observed before. Museum records, how- 

 ever, show specimens taken on April 4, 13, 16, 23, 26, 28 and 30. The 

 thoroughness of the field work in April over regions where they 

 later appeared makes it seem probable that they came later this 

 year on account of the backwardness of the season. The last mu- 

 seum record is November 5. Records of other states make it ap- 

 pear probable that they remain somewhat later. 



191. Ixobrychus exilis — Least Bittern. 



A not uncommon summer resident. They come later and leave 

 earlier than the last. Four specimens in museum taken between 

 May 14 and 28. Records from other states would make it probable 

 that they come somewhat earlier. 

 194. Ardc'i licrocUas hcrodias — Great Blue Heron. 



A common summer resident. Museum and field records show 

 residence from March 20 till September 15. Other states show 

 records which makes it seem probable that they come somewhat 

 earlier than this and remain somewhat later. 



196. Herodias egretta — Egret. 



After the breeding season is over, egrets, whose summer home 

 is considerably south of Kansas, will not infrequently wander over 

 the state. 



197. Egretta tJiula tliula — Snowy Heron. 



This heron likewise wanders over Kansas after the close of the 

 breeding season. 



200. Florida ccerulea — Little Blue Heron. 



This bird rarely strays over the state after the breeding season. 



201. Butoridcs vircscois viresceiis — Green Heron. 



A common summer resident. Museum and field notes show the 

 first arrival as April 27. They begin to leave about September 1; 

 the last record being September 16.
