Description
Excerpt from The Birds of Colorado The notes on migration given in the following table are designed to show the different time at which the same species of birds arrive at different places and altitudes in Colorado as compared with the time of their arrival in the same latitude farther east and at a lower altitude. St. Louis, Mo., is thirty miles farther north than Fort Lyon, Colo., and one hundred and twenty miles south of Loveland, Colo. Hence, according to latitude, the birds should arrive in St. Louis about the same time as at Fort Lyon. But it is found that in fact they reach St. Louis on the average about twelve days before they appear at Fort Lyon. The dates Of arrival seem to indicate an aver age difference Of six days between Fort Lyon and Loveland. The distance between these two places is one hundred and fifty miles, or an average movement for the birds of twenty-five miles per day. This agrees quite closely with the average of twenty-eight miles per day that was found to be the usual speed of migration in the Mississippi valley.
