On Making a Bird Census:


The census-taker is struck by the variation in his records from hour to hour during the day, irrespective of kind of territory covered and of his own degree of alertness. This fluctuation is due in large part to the fact that there are two daily periods of marked activity on the part of birds, namely, in the early morning, within an hour or so after sunrise, and in the late afternoon, about two hours before sunset. Of these two periods, that in the morning is the most impressive; in other words the observer, by selecting the earlier hours for his census-walk, will make the highest score and also the most representative one. It is quickly apparent that in comparing the enumerations for different days and for different localities allowance should be made for this daily double fluctuation in the visibility and audibility of birds.

It is the earnest recommendation of the authors that observers in a position to do so will get into the habit of taking bird censuses. The method here advocated is a practicable one; we believe it can be adopted to advantage by anyone possessed of a fair acquaintance with bird species. A 'collection' of census records will afford basis for much future satisfaction. On the one hand, is the pleasure of recalling to mind pleasant days afield spent among the most attractive things in nature; and on the other hand is the intellectual enjoyment derived from comparing bird populations in kind and size from place to place and season to season, and from endeavoring to account for the fluctuations which are shown, on the basis of all the factors known to control the birds' existence.
