This is the most common warliler around Lalvc Winona. In fact it is, 

 probably, excepting the song-sparroAV, the most common songster here. I 

 liave found numerous nests; generally in rather damp ground at the bot- 

 tom of a clump of weeds, about foiu- or five inches up. Wlieu you ap- 

 proach the nest of eggs the female will noisily drop over the side and 

 run away tlirough Ih.e weeds, from Avhich it is almost impossible to flush 

 Iier. "When their young are liatclied they resent intrusion, often flying 

 by you within three or four fei't. 



On the morning of July 23, I found a nest containing three eggs of 

 the Maryland Yellow-throat and one of the Cowbird. It was in a bunch 

 of Aveeds within six inches of the ground. The place was rather damp 

 and about twenty yards from the lalie shore. It was so cleverly con- 

 cealed I would never have found it had not the female jumped iip. I

 first trip in the morning the eggs were still unhatched but at 3 o'clock in

 liatched and anotlier almost out as the shell Avas chipped considerably. 

 I came back at 5 o'clock and tlie second Maryland Yellow-throat was out. 



On coming back next morning things Avere the same; tAVO birds and 

 one egg. The young ^Maryland YelloAV-throats kept their mouths open all 

 the time Avhile the CoAvbird never opened its mouth. The young Mary- 

 land YelloAA--throats were continuously struggling to maintain their place 

 and keep tlie C'oA^bird from smotliering them. 



On the 28th the extra egg had disappeared and AA'as not to be seen 

 around the nest. 



On tlie 29th things Avere as usual and on the 30th they AA'ere also the 

 same. On the 31st the last born Maryland YelloAV-throat had disappeared 

 and was not to be seen around the nest. The Cowbird and the remaining 

 Maryland YelloAV-throat had feathered out pretty Avell by this time. On 

 August 4 the Cowbird Avas occupying the entire nest and the Maryland 

 YelloAV-throat Avas sitting on the edge. They were both ready to leave. 

 In the afternoon at 4 o'clock the nest Avas empty. The vociferous cries
