Fall Migrations to Observe this Season

September 13, 2021

Posted by Lake Erie Nature and Science Center

From birds to butterflies, wildlife is on the move. Ohio’s geography of forests, grasslands and coasts, along with two large water sources—Lake Erie and the Ohio River—attracts a wide array of wildlife during fall migration. Here are Lake Erie Nature & Science Center’s top migrations to observe this season.

Monarch Butterflies

One of the most fascinating creatures in North America is the Monarch Butterfly. Each fall, millions of monarchs leave their summer breeding grounds in the northeastern United States and Canada to travel upwards of 3,000 miles to reach their overwintering grounds in southwestern Mexico.

To spot these winged migrants, look in lakefront woodlots or areas with plants still in flower such as asters or goldenrod.

Bats

Depending on the species, some Ohio bats such as the Eastern Red Bat, Hoary Bat and Silver-haired Bat migrate south in the cooler months when food sources become scarce. The best time to see them is around sunset or sunrise when it is warm and dry. While some bats fly relatively high, others are found closer to the ground and tree line.

Hummingbirds

The most common species of hummingbird in Ohio is the Ruby-throated Hummingbird. Weighing an average of 3.5 grams, these birds migrate from Ohio to their winter homes in Central and South America which includes a 500-mile non-stop flight over the Gulf of Mexico.

You can attract hummingbirds to your yard by hanging a nectar feeder with ¼ cup pure cane sugar per 1 cup water. Remember that during hot weather, sugar water ferments rapidly to produce toxic alcohol and should be changed daily.

Songbirds

Every fall, millions of birds migrate through Ohio on their way to overwintering grounds. During migration birds can travel hundreds of miles in one night. Birds migrating to Central America will fly the 500 miles across the Gulf of Mexico nonstop, leaving at dusk, which takes between 18 and 22 hours.

Local spots to observe songbirds during fall migration include Huntington Reservation and Wendy Park of Cleveland Metroparks and Cleveland Lakefront Nature Preserve.

Migration Challenges

The migratory journey presents several challenges for wildlife, especially songbirds. Most species of songbirds migrate at night and the lights on tall buildings can be disorienting. Collisions with buildings are a leading cause of bird fatalities during migration, and it is estimated that up to half a billion birds die each year from building collisions.

Lights Out Cleveland aims to protect migratory birds through volunteerism and advocacy. Since mid-August, volunteers have scanned the sidewalks surrounding downtown buildings to collect injured and deceased birds. Injured birds are brought to Lake Erie Nature & Science Center’s wildlife rehabilitation facility for treatment and eventual release back to the wild.

The nonprofit Lake Erie Nature & Science Center is the only wildlife rehabilitation facility in Cuyahoga County and provides its services 7 days a week at no charge to the public. For wildlife assistance, please contact 440-871-2900 or wildlife@lensc.org. Thank you to The Kenneth A. Scott Charitable Trust for supporting Lights Out Cleveland and the Center’s rehabilitation efforts.

That busy time of year…

As the summer season winds down, we all find ourselves getting ready for the school year or preparing for the cooler seasons to come. During this potentially hectic time, we are fortunate that it is also a great time to pause and look up at the evening skies after sunset. With Jupiter and Saturn in perfect viewing position, this is a chance to practice mindfulness and enjoy one of nature’s great and free spectacles.  – Bill

Evidence Of Rogue Planets Found

Astronomers, scanning data from the now defunct Kepler Space Telescope, have found evidence of 4 rogue planets. Rogue planets are planets floating free in space and not gravitationally bound to any star. Currently, these planets can only be detected by using gravitational micro-lensing. This technique detects the distortion of light from a distant star due to the effects of a gravitational field from an object in front of it.

The Midnight Sky

The Midnight Sky movie poster

This month we reviewed the movie “The Midnight Sky directed by George Clooney

A lone scientist in the Arctic races to contact a crew of astronauts returning home to a mysterious global catastrophe. While this is a decent sci-fi film, it focuses more on the human mind’s “inner-space” than outer space. I enjoyed it while I was watching it, but it may not stick with you for too long. In my opinion, not one to buy but absolutely worth a rent.

Wrap your brain around this…

Mind-blowing facts

We’ve all seen pictures or video of astronauts floating around on the International Space Station. Would it surprise you to know that gravity on the ISS is only 10% less than on Earth? Objects in the space station are essentially falling around the Earth.

Diagram of Newton's thought experiment on orbital motion

Objects in Earth orbit are traveling at such a high velocity that they are “falling” at the same rate as the curvature of the Earth. If you fired a cannon, the cannonball would curve downward and land some distance away.

If you fired it faster, it would land even further away. If you fired the cannonball at orbital velocity, or 17,500 mph, the ball would essentially fall around the Earth and be in orbit.

Mental Exercise

If you dug a hole all the way through the Earth from Bay Village, it would emerge about 1,000 miles west of Australia. If you then jumped into this hole, assuming there was no air present, it would take you about 42 minutes to reach the other side of the planet. You would accelerate to a velocity of 17,900 mph at the center of the Earth and gradually slow as you got the other side. You would eventually slow to a stop and be pulled back into the hole by gravity. This would continue as you were drawn back towards the center from either end of the hole. This back and force motion would continue essentially forever.
