Riding Ridges, Traveling Coastlines
Peak flights were witnessed this week along the ridges of the Appalachian Mountains and the Atlantic coastlines, marking the first strong pulse in the Eastern Flyway.
Riding Appalachian Ridges
Migration rates of up to 1,500 per hour were witnessed along the ridges of the Appalachian Mountains over the weekend, marking first strong pulse in the Eastern Flyway.
“I saw my first PEAK Migration today! In total, between 11 am and 1 pm I was watching for 75 minutes and counted 356 monarchs. I’ve never seen so many “at once.” Steeles Tavern, Virginia 9/29/18
The Appalachians are one of the best migration hot-spots in the eastern United States. Monarchs follow the ridges of the mountains. They can use “ridge lift” to gain altitude and then glide effortlessly along the ridges toward Mexico.
Traveling Atlantic Coastline
The Atlantic coast is another major migration highway. North and west winds blow monarchs to the coast, and the butterflies travel down the shoreline to avoid the ocean. This results in some of the best monarch-watching in the eastern US.
“I spotted 560 Monarchs over a five hour period from 2-7 pm. Today was a sunny beautiful day with temps in the high 60’s and a 10 mph westerly wind. The monarchs continuously flew by and sought out flowering plants where some famished monarchs spent the night roosting on the nectaring flowers. Amazing.” Long Island, New York 9/29/18
Moving Toward Mexico
Look at the peak migration map. It clearly shows the monarchs are moving toward Mexico. In the Central Flyway, south winds will hold the butterflies back until at least Saturday the 6th, when a cold front - with its north winds - is predicted to extend into northern Texas. Stay tuned!
