INSTALLMENT NUMBER FIVE in my series of answers to your bird questions centers on how birds who hunt locate their prey, and also some important tips on when we humans choose to feed birds. Ellen Blackstone of BirdNote, the daily public-radio show, will once again be our guide for exploring what’s going on as we look skyward.
Before we get started, the BirdNote backstory: In 2002, the then-executive director of Seattle Audubon heard a short public-radio show called StarDate. “We could do that with birds,” she thought. In 2005 the idea became a two-minute daily public-radio “interstitial” (short program). I recently asked BirdNote to help answer the recent questions you’d asked me.
Parts of Ellen’s answers below are in 2-minute audio clips to stream (all in the green links–or you can read the transcripts at those links if you prefer):
what senses do birds use to hunt?Q. How do hawks and other hunters such as owls find their prey from such a distance–is it all about eyesight, or is smell involved or sound or what?
A. Sight! Sound! Smell!
Sight: The expressions “eagle eye” and “bird’s-eye view” weren’t coined without reason.
The eye of an eagle is one of the most sensitive of any animal, and may weigh more than the eagle’s brain. Learn more on that.
We do know that visual acuity is keenest among birds like flycatchers and hawks, which must pick out small or distant moving objects. We also know that birds’ eyes are about three times sharper than those of humans. This two-part show from the BirdNote archive goes into more detail: Listen to or readPart 1 and Part 2.
Sound: The barn owl’s ability to locate prey by sound is the most precise of any animal yet tested.
Smell: Diminutive seabirds called storm-petrels are olfactory

“Like the week in Lake Wobegon, it’s been mostly quiet,” says Ellen. “For the most part, the birds have stopped singing.” Turning their attention away from establishing territories, finding mates and having families—what the songs were mostly about—they’ve shifted focus. “Some birds even lose the ability to sing after the breeding season is over,” she adds (learn more about that in this BirdNote show and transcript).In the Q&A that follows, Ellen’s answers contain green links to audio files from BirdNote’s archive that you won’t want to miss.

So what are the birds doing as we enter midsummer?A. Many birds–wrens, robins, and others–may raise more than one brood in a breeding season. Depending on what part of the country you call h
In nature, Ilex verticillata or winterberry hollies inhabit the edge of the woods or even wetlands—not typically choosing to make their home where they’d suffer extra-dry conditions like the ones this year.Even with the occasional off year, I would not be without winterberries (or at least not intentionally). I hope the birds can make do with a quarter-crop, feasting instead on a bumper lot of crabapples and many seed-bearing things, from grasses to conifers. Fingers crossed.Learn more:Pretty, pretty: A gallery of winterberry hollies What birds like: 11 steps to making a bird garden Listen ins
Yes, said my friend Ellen Blackstone of the BirdNote public-radio program, who has been the tour guide for our ongoing series of bird stories here on the blog. (Browse all past installments.)The part of the bird’s brain that’s used for singing shrinks to lighten the bird’s body mass in the offseason, she explained (and here’s the link to hear more on that). In fall and winter, there is no mating ritual; no need to stake out a territory.Many birds can still s
P EOPLE LIKE TO ASK ME QUESTIONS, GARDENING QUESTIONS. It’s been happening for a couple of decades, and lately, well, lately it’s getting worse (better?). More urgent, you might say, as in more urgent garden questions than ever.

Why isn’t the wild turkey our national bird? A. In 1784, that wise old Ben Franklin groused to his daughter, after the fact, about the choice of the bald eagle as our national symbol:“For my own part I wish the Bald Eagle had not been chosen the Representative of our Country. He is a Bird of bad moral Character. He does not get his Living honestly. …Too lazy to fish for himself, he watches the Labour of the Fishing Hawk; and when that diligent Bird has at length taken a Fish, and is bearing it to his Nest for the Support of his Mate and young Ones, the Bald Eagle
“They’re related to crows,” I said on the phone one morning to a friend, who was noting both the large numbers of Cyanocitta cristata this winter—and how much loud-mouth behavior that’s amounting to at his feeders.“Really?” he said, and then I thought what I often do when a “fact

They cover a very wide range of distances, but here’s a hint at some of the impressive extremes:Our humble barn swallow is a true long-distance migrant, and may winter as far south as southern South America, often returning to the same area year after year. Imagine: the sprightly bird that nested in the eav
“You may not (yet) know the difference between a bird’s song and its calls,” says Ellen, “but the bird sure does. It’s often sending a special message to another bird–or other birds–of its species.”In the Q&A that follows, Ellen’s answers contain green links to audio files from BirdNote’s archive that you won’t want to miss, since we’re talking sound this time. I recommend making a big pot of tea, and planning to spend some time with these answers and the corresponding sounds–it’s like a beginner’s course in birding by ear.

Obviously nobody’s using my nestboxes to raise a family right now—should I take them down? A. Yes, it’s time to take down your nestbox, at least temporarily, and clean it out. It’s a good idea to wear gloves and a dust mask while you do this. Use hot soapy water and a scrub brush, and rinse it with a pot
Remember the BirdNote backstory from last week: In 2002, the then-executive director of Seattle Audubon heard a short public-radio show called StarDate. “We could do that with birds,” she thought. In 2005 the idea became a two-minute, seven-day-a-week public-radio “interstitial” (as short programs are called) that recently caught my ear. I asked BirdNote to help me answer all the recent bird questions you had asked me. (In case you missed it last week, for installment Number 1, we tackled this subject: How do birds make themselves at home—even in winter?)Parts of Ellen’s answers below are in the 2-minute clips you can stream (all in the green links–or you can read the transcripts of each episode at those links if you prefer). Here we go:how do hummingbirds do it?Q. The miracle of hummingbird migration amazes all of us. How do they manage to migrate from the northern United States all the way to Mexico and beyon
Ellen Blackstone of the BirdNote team (who describes her job there as “writes/edits/finds photos/posts to the website/sits in on recordings”—sort of like my job at A Way to Garden) was kind and patient enough to be our teacher. Remember, parts of each answer are in the 2-minute clips you can stream (all in the green links–or you can read the transcripts of each episode at those links if you prefer). Here we go:nest, versus roostQ. The topic of where birds prefer to live, and especially the role of the nest in their lifestyles, seemed to provoke my readers’ curiosity—and also probably some misconceptions. What’s “home” to a bird? A. The great number of migratory species are all away from their nests–some as far as a different continent–during the nonbreeding season. Even among the residents, the majority of birds do not use their nest as a home but only a place to raise their young.Exceptions would be some hole-nesters that roost in their cavities throughout the year, but they are a real minority. Those might be chickadees or their cousi

I’ve read that flamingoes’ plumage may be more or less colorful depending on their diet, but is this true of other bird species, too?A. What on earth does the lowly house finch have in common with the elegant, long-legged flamingo? They are what they eat. In color, that is. The carotenoids in their diets affect what color they are. Carotenoids are the same pigments that give oranges and carrots–and brine shrimp–their color
