Do
Monarchs Migrate Across the Gulf of Mexico?
Contributed by Mr. Don Davis
Evidence that monarchs
MIGHT cross the Gulf of Mexico
Sightings:
- We know that monarchs
can cross large bodies of water. Monarchs are seen
by boaters crossing Lake Ontario, for example.
- There
have been sightings of groups of monarchs roosting on oil platforms
in the Gulf of Mexico. When I flew over the Gulf in 1997, I was amazed
at the number of oil rigs and other platforms in the Gulf. Thus, there
are many opportunities for tired monarchs to rest!
- Also,
famous monarch biologist Dr. Fred Urquhart reported seeing monarchs
flying in off the Gulf of Mexico as he stood on Mexico's Yucatan Peninsula.
Recoveries
of Tagged Monarchs:
- I have tagged
monarchs in Presqu'ile, Ontario that were recovered directly across
Lake Ontario at Rochester, New York. That's a distance of nearly 50
miles.
- I had a tagged
monarch recovered on an oil rig in the Gulf, about 100 miles south of
Galveston, Texas.
- Ted McDonald of
Port Hope, Ontario, had his Port Hope tagged monarch recovered in Havana,
Cuba (Urquhart tag - 1960's). Port Hope is on the north shore of Lake
Ontario. The distance to Cuba is about 1,500 miles.
