Hummingbirds and Hurricanes

Ruby-throated Hummingbird male.

This morning I helped trap hummingbirds for banding at Seven Islands State Birding Park in east Tennessee where local Ruby-throated Hummingbirds are preparing for migration and others are stopping to feed enroute to their wintering grounds in Central America and Southern Mexico.  At the same time, three hurricanes are churning in the south Atlantic, and as I write, hurricane Irma, originally a category 5 hurricane that has devastated many islands in the Carribean, is barreling down on Florida.

Knowing that Ruby-throated hummingbird migration is in full swing, I have wondered how these hurricanes have affected their migration.  I asked my friend and east Tennessee hummingbird expert, Mark Armstrong, to share what he knew about storm affects on migration. He answered with these comments:
"Unfortunately I don’t know much about their [hummingbird] survival in a storm.  I’ve heard of birds making landfall on the fringes of other storms and arriving thin and exhausted.  I’ve also read that migration from an evolutionary standpoint is actually across a broad front and a prolonged period so that some part of the population may be affected by adverse weather the majority will not be and survive.  I also keep thinking about Dr. Buehler’s Golden-winged warblers. They were at their breeding territories, left when tornados were heading their way, some went to the Gulf coast and one went back to Cuba.  Then they returned to breeding territories after the threat passed.  That is amazing and we really don’t know what birds may be perceiving and if they are capable of moving away from a danger like a hurricane.  Any small bird I can’t imagine would survive a direct hit from a storm with extremely high winds."

I, for one, am glad that the local hummingbirds frequenting my yard are hanging around and hope they will wait to leave until the many storm threats pass.

Meanwhile, we had a fun surprise during our banding session this morning at Seven Islands.  You may think that the hummingbird pictured above is a mature male Ruby-throat.  But surprise--this is a juvenile!  Normally, we expect to see juvenile males in their first year with scattered red throat feathers like the one pictured in image three or we might see small clusters of three or four red feathers as their gorget begins forming.

This first year male had an almost fully formed gorget, which Mark described as a rare occurrence in his experience.  Mark has banded over 4000 Ruby-throated hummingbirds since he began banding hummingbirds in 2005.  The juvenile pictured had white tail feather tips and other attributes that are the identifying characteristics of juveniles.

Most of our hummingbirds will leave Tennessee by the end of September with some late individuals departing by the second week of October.  Remember to leave at least one feeder out to feed our wintering hummingbirds that come from the west.  These birds often arrive from October to December.  If you should have a hummingbird at your feeder after November 1st, contact Mark Armstrong at Woodthrush@bellsouth.net or 865-748-2224.

Hummingbirds and Jewelweed

Recognize this watercolor?  It's the hummingbird painting you see in my blog banner!  

Maine's Wild Seed project contacted me earlier in the year to inquire about using one of my hummingbird paintings with their article on Jewelweed's beneficial relationship with hummingbirds. Life gets busy and after we made arrangements, I actually forgot about it! What a delight to see this beautiful spread of my "Hummer and Jewelweed" painting in the latest publication of Wild Seed, Returning Native Plants to the Maine Landscape. 

Maine's Wild Seed project educates people about the important relationships between native plants and animals and how these relationships support each other.  Their magazine is beautiful, a feast for the eyes and informative to read.  They also have tons of helpful information and resources available on their website:  http://wildseedproject.net/  Pay them a visit and plant native plants!

Watercolor Nature Journaling Workshop

Join me for a fun day of exploring nature with watercolor on April 8th at the Chota Recreation Center, Tellico Village in Loudon, Tennessee.

Nature journals are the earliest source of information that we have about our natural world.  Holding a journal in one's hand evokes emotion and awe because we innately relate to the sensory details captured in the artists words and images.  The added bonus to creating our own journals?  We see and enjoy more deeply and that comes with calming health benefits!

Join me for a relaxing day of exploring watercolor and nature. We will review helpful sketching techniques, use of values, basic watercolor washes, negative painting, representation of sky, clouds, rocks and trees, and choice of colors for the season. Using all our senses to enhance our observations, we'll leave our traditional artist fears behind and enjoy a day of exploring nature with watercolor.

The workshop is sponsored by the Art Guild of Tellico Village.  Visit this link to sign up!
