Arrival, Peak, and Departure Weeks with TSS

for the Spring and Fall Seasons


Procedure: Enter below a species name, and choose the number of hiatus TSS weeks (0-8) for the analysis. (A hiatus week is an intervening week with zero TSS.) This allows you to exclude rogue bird sightings in the output. A table will be presented spanning the entire length of the project with a listing of arrival, peak, and departure weeks, as well as the TSS for the species for those weeks. The program divides the year up into Spring (Weeks 1-26), and Fall (Weeks 27-52). Knowledge of which species are migratory is important. A search for non-migratory species and summer residents will result in less useful output.
