Readers’ wildlife videos and photos

July 31, 2018 • 7:45 am

It’s time to refill the photo tank. I have a fair few contributions, but I could always use more, so send in your good animal, plant, astronomy, and other nature-related pictures.

To add to Stephen Barnard’s hummingbird photos of two days ago, he’s sent two videos of hummingbird fights (rufous vs. black-chinned). Be sure to watch them enlarged:

“Combat”

“Kung fu” in which a rufous hummer pulls a tricky move:

Reader Justin Zimmer sent some plant and animal photos. He didn’t enclose IDs or captions, so put those below if you know them:

  1. Third photo butterfly is pipevine swallowtail (Batus philenor). Last photo butterfly is clouded sulphur (Colius philodice).

    1. Nice photos. All four Peacock butterfly photos are of different individuals: Each has distinct wing damage and color pattern. The Peacock is unusual in that males are territorial, at least where I live. In the mid-hours of the day after feeding they will perch on low plants and drive other males away, sometimes batting their wings together in the process. A given male will return to defend the same spot on successive days. The male peacocks are waiting for receptive females with which they can mate. Presumably males that drive off rivals and win territories nearer host-plant patches (sources of young, unmated females) are rewarded by more frequent mating.

  2. Ref that cactus flower and also the daisy-like ones farther down, both are red inboard and yellow farther out. Reminiscent of Gaillardia, too.

    So here’s a question: is this the way most combo red/yellow flowers are? Any example of the opposite situation that comes to anyone’s mind?

    1. If I understand your question, there’s some dahlia, begonia, and camellia that have red petals and yellow stamens that really stand out, Butina assume that they’re probably not wild types. Would the colors serve different purposes depending on their location? One act as a botanical “runway” guide for landing, the other as the “eat here” indicator, and could those signals be reversed, depending on the pollinator?

      1. Thx! But if I get your reply correctly, those examples have all red petals, right? I’m looking at petals that have one color outboard and another on the inner end, and what I wonder is if in these cases perhaps there’s chromatographic effect, with one pigment running faster than the other. An extremely cursory search turns up that yellows are carotenoids, while reds are anthocyanins. altho there are some red carotenoids too.

        Probably just an off-the-wall idea.

  3. All these images are a great display of summer colors. The butterflies fight the flowers for our attention.
    The hummingbirds are becoming active as we see from Steven’s videos. They are feisty little creatures which provide us with some wonderful summer entertainment.

    1. And the sound that hummingbirds put out when they fly past your ear, as one did past my ear last month while sitting on a deck with hummingbird feeders, is unforgettable, too.

      1. Right? No matter how frequently I hear them (which is often, considering I have feeders out), my first thought is always, “acck, it’s Waspzilla!” Obviously they get a kick out of that…

  4. Gorgeous colors in the photos today.

    I’ve been enjoying the hummer fights as well. Good job on the video capture; those little suckers are hard to track.

  5. Cool captures, Stephen! Love the way that even in slo-mo hummers are fast!

    Beautiful butterfly/flower compositions, Justin. That penultimate one is just glorious!
