Yardus Swainsoni Oporornis agilis Contemp views Fall singing of the Dreos. Anthus ludovician (dawn on) 1875, Sept. 11 Cold and very cold this falling to 40. Off at 5.30 A.M. meeting Will Stoner in the Swamps he having missed me at the house. No large Birds were wanting me went in immediately for specimens but had very poor luck, The only bird that I got worth Winning was an adult B G. Trichas in most beautiful fall plumage. Shot and spilt a Yardus Swainsoni the first. Saw a little company of Paula Arm. and shooting on found in almost distinct of any saw fine feathers. Saw also Oporornis agilis, I have seen several birds during the week that I refuted with some doubts to this species but this time there was no mistake as I got within 6 ft of the bird; it was uttering its peculiar and indescribable note (a Bird a bird shape almost vibrating sound that has withal a sort of metallic ring to it) and another in the same thicket kept answering it. Dreos flrifess and U. montanaensis were both in full song in the pine swamp and the notes of both but of the latter especially seemed to me to possess a compass and sweet completeness lacking in the spring! Possibly the fine pure air at this season may assist the effect or lend vigor to the performer. The Sparrows are now moultling and in very poor plumage. D. striata is not very abundant yet, Saw two Catlipes birds! It is remarkable that this species which arrives before B. minimus should be the last to leave. The swamps are very dry and we shall probably have no rain this fall.
