In The Path of The Storm

8 September 2017, 10am EDT:

Many of us are watching with morbid fascination as Hurricane Irma churns through the Caribbean on its way to Florida.  Even if we aren’t in Irma’s path, we know people who are and we’re worried.

After Irma passed over the U.S. Virgin Islands (USVI) I searched the Internet for footage of St. John, USVI, where I visited in January 2015.  I found information in this USA Today article with links to the USVI Hurricane Irma Alert Facebook page.  Beyond the obvious human suffering, I am struck by how brown the landscape is now.  All the leaves were blown off the trees.

Where are the birds?  What did they do during the storm?

Fortunately birds have strategies for coping with bad weather including:

Shelter in Place

Like us, birds hide out of the wind and rain and wait for the storm to end.  They use man-made structures, thickets, and deep valleys where the wind is less intense. Their strategies are described here in Shelter From The Storm.

Evacuate

Birds can sense when a storm is coming and often evacuate before it strikes.  A study of golden-winged warblers found that they left Tennessee a day ahead of a tornado: Warblers Fled Tornado One Day Ahead.  Land birds in Florida can move northwest as Irma approaches but the birds on Caribbean islands had nowhere to go.

Fly In the Eye of the Storm

Sea birds have a third option.  As they fly in search of a calm spot, they end up in the eye of the hurricane where they travel with the storm until the winds die down.  This NASA image shows that the eye of Irma on Sept 5 was larger than both Anguilla and St. Martin so it was probably a relatively safe place.  However, the hurricane won’t lose power until it’s over land so the sea birds may be exhausted when they finally stop far inland.

People and birds in the path of Hurricane Irma are all getting ready.  I think of my friends and family in Florida.

    My husband and I vacationed in the Caribbean shortly after one of the hurricanes. There seemed to be very few birds compared to other years.

    Also, we visited Cancun shortly after Hurricane Rita. The animals that lived in small sheltered coves and wild spots were missing. It took several years for the populations to rebuild.

    Hoping for the best in Florida! I am moving to Sarasota area soon and enjoying the beaches and birding.

    The north wind doth blow
    And we shall have snow
    And what will poor robin do then?
    (poor thing!)

    He’ll hide in a barn
    To keep himself warm
    And tuck his head under his wing.

    I think I read somewhere that there’s one species of bird (an albatross?) that uses the winds to help them on their migration. Like a slingshot. Not the right time of year for them though. Perhaps others use that strategy.
