The Monarch Butterfly

I was talking on the phone with Tom, looking out the window at my view from the 18th floor when I saw a Monarch Butterfly.  They've begun their migration.  She, of the darker color, was just flapping her wings heading back to Central America.  I kept looking to see if there were more coming so I could get a photo, but no luck.  So I went off to the park to find one, but there were none there.
The Monarch Butterfly travels each year, spring and fall along the East Coast about 2500 miles.  Their life span is only 2 months.  So no single monarch completes the journey.  Unfortunately, deforestation of their habitat has drastically reduced their numbers and they are being considered for endangered species status.  I'll keep looking and cheering them on.  I'd put a flower pot on my windowsill for them to rest but right above the front door on the eighteenth floor where it gets windy.  I don't think so.
