Margaret Morse Nice (1926) made a very elaborate study of the happenings at another nest; her account, containing many interesting observations, to which the reader is referred, is too detailed to be quoted here. Her table shows that she watched the nest for a total of 26-1/2 hours, spread over a period of 9 days; during this time, the young were fed by the male 118 times and by the female 91 times; the average rate of feeding was once in 7.8 minutes; the female brooded 33 times for a total of 352 minutes; the faeces were eaten 8 times and carried away 38 times. Aretas A. Saunders (1938) writes: "After the young have left the nest, they are much in evidence in the forests. As soon as this happens, whatever territory there was is abandoned. The young wander away, keeping together, and the parents care for them, feeding them frequently for the first few days. Both sexes feed the young, but after a day or two only the male is likely to be in attendance. Young in this stage are easily located by the incessant hunger calls. These calls consist of three or four high-pitched notes, _tsee tsee tu_--_tsee tsee tsee tu_--_tsee tsee_, etc. I cannot distinguish the call made by young of this species from those made under similar circumstances by the young of the black-throated green and blackburnian warblers." I have also received from Mrs. Doris Huestis Speirs and from Mrs. Louise de Kiriline Lawrence very full reports on their observations at two nests of magnolia warblers in Ontario. Many of their observations were similar to those mentioned; however, the following should be noted here: Mrs. Lawrence found the incubation period to be about 11 days, incubation and brooding being by the female only. The young were fed by both parents by regurgitation for the first 3 days, and after that on solid food, mostly caterpillars; in 49 minutes, the male fed them 7 times and the female 5 times. During 5-1/2 hours, the male ate or carried away the fecal sacks 15 times. The young left the nest on the ninth day after hatching, and were fed by their parents up to the twenty-fifth day after leaving the nest; after that they were seen feeding themselves. Mrs. Speirs kept an accurate record of the brooding periods, which were from 8 to 45 minutes in length, but seldom less than 20 minutes, the female leaving the nest for periods of from 3 to 15 minutes. At times she closed her eyes and seemed to doze; occasionally she rose and turned the eggs with her feet or bill. The presence of birds of other species approaching or flying over did not seem to disturb her but the movements of a red squirrel in the vicinity kept her alert. The story of this nest ended in tragedy; some predator destroyed all but one of the young, the female finally disappeared and eventually there was nothing in the nest but an unhatched egg. A sharp-shinned hawk had been seen flying over.
