Is there historical data/graph out there that shows Colorado migration periods/species occurrence? For example:
10% (early migrants) of Colorado early spring migrants occurs between Apr-x and May-x dates 80% (most migrants) of Colorado spring migration occurs between May-x and May-y dates 10% (late migrants) of Colorado late spring migrants occurs between May-x and June-x dates Same for Fall migration. If we have that data then what species fall in early, most, late windows? Don't want generalizations--be interested in seeing what data shows.
