P. M. – B & I, sitting watching a pair or wrens. The male, who has been around several days, had finally found a prospective mate, and was, with mad almost incessant singing trying to persuade her to come and inspect the box I had put up for them. She played reluctant for a while, but gradually he got her closer and closer, and finally then he sat on top the box, fluttering his wings and coaxing. At last she flew in, and while she was inside, he fluttered his wings and made tender little lisping sounds – as much as to say “What do you think dear? Isn’t it pretty nice – won’t we be happy here?” – Presently she came out, and apparently approved, for he burst into song again. She flew to the top of the apple tree next door, - a moment later, a sparrow appeared [and] at once the male commenced a strident warning call, which he kept up until the sparrow flew away.
