"Late dates of spring departure from Central America are: Honduras--Tela, April 24, 1930. Guatemala--passim (Griscom), April 15; Motagua Valley, near Los Amates, April 30, 1932." Dickey and van Rossem (1938) record it for El Salvador as a-- rare fall migrant, but common winter visitant and spring migrant in the Arid Lower Tropical Zone. Although found from sea level to 3,500 feet, the species is much more numerous below 2,000 feet than above that altitude. Dates of arrival and departure are October 12 and April 24. * * * In December perhaps a dozen all told were seen on Mt. Cacaguatique, always as single birds with small flocks of Tennessee and other warblers. By January they had become very common, and at Puerto del Triunfo during the whole of that month and in February at Rio San Miguel almost every flock of blue honey creepers was accompanied by one or more magnolia warblers. There was no noticeable decrease in numbers until after the middle of April, and even on the 24th (the last date on which the species was noted) they were recorded as common.
