Breeding Birds of iVlarshall Co., III. 



In the Ornithologist and Oologist, 

 Vol. XV, Page 113 (August, 1S90) I 

 published a carefully ])repared "List 

 of Birds Breeding in Marshall Co., 

 fUinois." 



Now, 22 years later, 1 desire as the 

 lesult of those years of experience 

 and observation to supplement that 

 list and to amend the same in the fol- 

 lowing jjarticulars, that it may be 

 brought down to date and made as ab- 

 solutely accurate as possible. Twen- 

 ty-two years is a long span and part 

 of the breeding season of every one 

 of these years was spent by me in the 

 field within this county. Many changes 

 have worked amongst the birds and 

 some new species added. The changes 

 that I desire to make in this list are: 



Xo. 131, Hooded Merganser, ( Lajih- 

 odytes cucullatus). An article publish- 

 ed by me in The Oologist, Vol. Xo. 3 

 (March, 1912) details all the new dis 

 coveries with relation to this species 

 to date. 



Xo. 132, Mallard. (Anas boschas). 

 Several sets of the eggs of this species 

 have been taken within the rounty 

 since 1890. 



Xo. 144, Wood Duck. (Aix sponsa). 

 Rai)idly becoming a very rare breeder 

 — now but a few pairs nest within the 

 county where formerly there were hun- 

 dreds. 



No. 149, Lesser Scauj) Duck. (]\Iarila 

 affinis). This bird even yet rare oc- 

 casionally remains to nest here. I 

 have seen the j'oung. 



No. 194, Great Blue Heron. (Ardea 



herodias herodias). There is but one 

 small herony left within the county, of 

 prol)ably a coui)le of dozen pairs. It 

 won't last long. The Chicago Sani- 

 tary District Water has killed the 

 laiger trees in the river bottoms ami 

 they have no place to nest. 



Xo. 19G, Egret. (Herodias egretta). 

 Xot now seen in the county at all. 

 Formerly migrated by here in Thous- 

 ands and a few nested with us. Xot 

 one seen here in the past five years. 

 The last known nests near here were 

 in a larger herony of the Great Blue 

 Heron. There were about a half dozen 

 nests of this species, located at the 

 head of Hennepin Lake ten miles 

 north of the Marshall County line. All 

 the birds were killed by plume hunt- 

 ers in 1907. 



Xo. 20G, Sandhill Crane (Grus mexi- 

 cana). A pair of this si)ecies for a 

 number of years between 1830 and 

 18.t0 had their nest on the farm now 

 owned by my cousin, IVz miles north 

 and one-half mile east of the i)resent 

 Washburn School house. This is at- 

 tested to by two of my uncles who 

 lived on an adjoining farm, knew the 

 birds well and saw both old and young 

 birds and likewise saw and described 

 the eggs to me so accurately there can 

 be no question as to the authenticity 

 cf the record. 



Xo. 208, King Rail (Rallus elegans). 

 This bird I have ascertained to be a 

 common breeder here. I have taken 

 numerous sets of its eggs. 



Xo. 212, Virginia Rail (Rallus vir- 

 ginianus). This is a rare breeder here. 

 Wm. E. Loucks, formerly of Feoria, 

 111., and now of San Francisco, Cal., 

 photographed and took a set of nine 

 eg,i2:s while the writer was present in 

 the southern part of the county. May 

 7th, 1899. A half tone photo of this 

 nest and eggs may be seen by turn-
