FEMALE BLACK-THROATED GRAY WARBLER FEEDING YOUNG Nesting Habits of the Black-headed Grosbeak BY ANNA HEAD OES the same pair of birds return to their old nesting-site? This is a question difficult to determine, as, from the nature ot things positive evi- dence is almost impossible to secure. In some cases a ring has been fast- ened about the leg of one of a pair, and so it has been proven that he returned several years in succession to the same locality. But from slight indications point- ing in the same direction, even though no positive proof is forthconfing, I am inclined to think this is commoner than usually supposed. The evidence which has convinced me may not be so cogent to another as to myself. It depends chiefly upon individ- ual traits of character and of song observed for two successive years in a small val- ley in Mendocino county. The bird to which I paid most attention was the black-headed grosbeak (Zamelodia melanocephala), and at the end of the first sum- mer I felt personally acquainted with several pairs. In one pair the female was brave and did a large part of the feeding, brooding the birds willingly in my presence, while the nmle circled about and sang inces- santly. This pair chose a damp willow thicket, the home of the chat, for their nest, and placed it rather high on a swaying twig of willow, stayed by two cross- ing blackberry vines. I had the pleasure of watching the whole course of rearing the young, and saw where they were led off to the right along the edge of the swamp, while still totally destitute of tails and very downy about the head. This I consider a rather unusual nesting site, as the grosbeak seems to prefer dry hill- sides and manzanita, madrone, or hazel bushes. So when the second year I found
