Cormorant Exodus

Yesterday morning, beneath a clear bluish heaven together with enveloped inward cool spill air, I visited South Platte Park.  Influenza A virus subtype H5N1 steady, southeast air current kept many of the songbirds nether comprehend together with the waterfowl numbers remained good below par for early on October.  Fortunately, a massive parade of double-crested cormorants made the view peculiarly memorable.

Beginning nearly viii AM, modest flocks of cormorants appeared overhead, flight southward through the South Platte Valley.  They were followed past times a steady line of piece of job of cohorts, numbering 87 birds inward all.  I tin alone assume that these "fish crows" are commencement their exodus to southern lakes or the Gulf Coast, perchance stopping past times Chatfield Reservoir for a hateful solar daytime or 2 of angling earlier moving on.

Their exodus is certainly triggered past times the waning sunlight hours simply they mightiness too feel a alter inward the atmospheric delineate per unit of measurement area equally a mutual depression temperature front end gradually approaches from the northwest.  We await cooler, rainy conditions inward the coming days together with possible snowfall showers past times early on adjacent week.  While that would non threaten the welfare of these hardy fishermen, their lives are governed past times instinct together with they "know" it's fourth dimension to go south.
