Example time-series graphs of bird captures at Manomet for four different species from four different trend clusters. Matthew D. Kamm Trevor L. Lloyd-Evans Maina Handmaker J.

Some species are unambiguously increasing or declining, while others show more complicated patterns. Lincoln’s Sparrow data is from spring migration, all others are from fall.</p> 2019-09-06 17:41:52 spring migration interannual variation fall migration Other species landbird populations cohort size observation error species groups 40 years 2015.
