Birds of Cape Ann: Mourning Doves and Why Birds Fluff When Cold

While writing this post and listening to recorded songs of Mourning Doves, I was immediately transported to my grandparent’s summer cottage on Cape Cod. Their home was sited on a bluff overlooking Cape Cod Bay. Adjacent to the house was a tumbled and scrubby overgrown field and, only a sort walk down down the lane, the freshwater Hiram Pond. There was no shortage of bunnies and birds, toads and turtles, along with the occasional frog and fox. From a child’s point view, it was pure paradise. Mixed with the sound of the surf, imprinted forever is the familiar song of Mourning Doves cooing at the first light of dawn. For much of the day the nesting doves remained hidden in the tangled undergrowth. Then in the fading rosy light of day’s end, their gentle song was heard again mixed with the laughter of rambunctious family feasts on the screened porch my grandfather had built.

Mourning Doves during the winter months are not calling to their mates but instead are struggling to survive the cold temperatures and sparse supply of food. Our bird feeders are filled often during the week, primarily with safflower seeds. As I have explained in previous posts, squirrels, which can be a real nuisance at feeders, typically are not interested in safflower seeds. Suet and such invites rats, rabbits, and raccoons, which in turn draws coyotes.

Feathers are insulating and by fluffing, the bird traps pockets of air to hold in body heat and keep out the cold. During warm weather, birds press their feathers close to their bodies to eliminate the insulating air pockets to allow heat to escape.

When the bird is incubating eggs, the insulating properties of feathers can be a drawback because the feathers keep some of the bird’s body heat from reaching the eggs. The bird either sheds some its breast feathers naturally or pulls them out to expose bare skin.  The exposed area is called a brood patch.

Addendum today ~ So sadly, my husband found beneath our kitchen window this morning a beautiful Mourning Dove. For the past several months we’ve had half a dozen doves, or what looked like three pairs, nestling in the pear trees and at the feeders. Our dead Mourning Dove seemed perfectly intact, except for a few drops of blood on its head. The single greatest threat to songbirds visiting our backyards are collisions with glass.  I never thought of our wind- and weather-worn original-to-the-house 1850s window glass as potentially hazardous. Time to rethink our little backyard sanctuary.

    move the bird feeder away from your house and they will not fly into the windows and kill them self’s.

    My female zebra finch always plucks a patch when they’re sitting on eggs. I never knew why. I just figured she was wearing a bald spot by sitting. Thanks for the info.

    Hi Kim,

    I emailed once before with a picture of a coyote in our back yard. You have such beautiful pictures on GMG and seem to have a wide knowledge of wildlife and particularly birds.

    We have an artist friend from Minnesota visiting us in the spring. He specializes in water foul and has been awarded the duck stamp prize several times. He asked us what kind of water foul he may be likely to see or to look for when he is here on Cape Ann.

    Can you direct me to a site or a list for that? I would appreciate it.

    Thanks so much.

    Hi Sandra,

    Thank you for your kind words re my photos.

    I think what would be helpful to your friend when he is googling is that he includes the word Essex in his search. Here are several great sites that I know of and there are more:

    I hope this is helpful Sandra.

    Readers, please add any sites you would like to see included here.

  5. Lovely photos of some beautiful birds.

    You write so eloquently about your wonderful childhood memories on the Cape that I feel like I’m right there! Mine are of a smaller Cape, Gloucester, of course… Good Harbor Beach, and my grandmother’s home on top of Mt. Vernon St. These wonderful memories sustain me, even today.
    Hearing a sea gull cry, while shopping in Portsmouth is music to my ears!

    It’s no wonder the doves were “fluffing.” It’s been below zero the past two mornings. Enough already!

    I love your informative posts and lovely photographs, Kim. You are truly talented. Keep them coming.

      Thank you so much Leslie- very kind of you to say.

      Too cold–I am trying to “hike” around our neighborhood to get in shape for 5 mile hike in Mexico and my knees freeze before i get very far. Could use some feathers or fur–doubling up on pants!

  7. Patti Amaral says:

    Just beautiful

  8. Dave Moore says:

    It is always hard losing a bird friend…It may be glass but again ir may be something else never know for sure…I watched a sparro this way on my window sill just looking around trying to get out of elements opened the outerwindow glass and he moved in by the screen think liked the heat went to get some bread crumbs was gone by the time I got back…Thanks :-)

  9. What month is your trip to Mexico, Kim? I hope it’s soon, so you can get a break from our severe winter. We could all do with a bit of warmth and sunshine.

    • Kim Smith says:

      Leslie I am leaving in a week!!!!

      I will be in the mountains in an unheated hotel where the temperature goes down to 30 degrees at night–I’ve been forewarned and will be traveling with winter coat, extra pajamas, and wearing lots of layers as it may go up to 55-60 during the day. It’s going to be the adventure of a lifetime, in more ways than one!

      I am hoping/praying it will be sunny–no sun = no butterflies!

  10. Leslie Y. De Vaney says:

    Well, that climate is not quite what I envisioned when you said, Mexico.
    Can’t wait to hear about your trip!

  11. Leslie Y. De Vaney says:

    I’ll be sure to check it out.

  12. Patricia says:

    I have a fluffed up dove on my back deck – hasn’t moved in an hour & 20 minutes. It is very cold & windy out & I feel very bad for it. Can I put anything out there to keep it warm?

    From Pennsylvania

    • Kim Smith says:

      Thanks for writing Patricia. No, the dove is keeping itself warm by fluffing out its feathers. Is it positioned in a somewhat sheltered spot in your garden?

      I find Mourning Doves love safflower seeds and provide plenty of it, especially during this never-ending winter, now spring!
