Mourning Doves

Mourning Dove - male

A couple of days ago we were lucky to catch a pair of Mourning Doves. We had all been sitting in front of the banding ‘lab’, the base of operations for the station, and watching a trio of doves wheeling and chasing each other about the cul-de-sac loop of the road in front. As we looked on, they suddenly swooped around and came down low, and then flew into the open net we could see from where we sat – bang-bang-bang (I say bang, but actually it’s a relatively gentle impact, as much as it can even be called an impact; maybe a better word would be ‘foop’, but foop-foop-foop doesn’t have the same sort of rapid-fire imagery). Myself and one of the other volunteers took off sprinting – Mourning Doves are large enough that they don’t typically stay caught long in a net designed for sparrows and warblers, and one of the three indeed escaped even as we madly dashed toward them. And the doves are caught rarely enough for them to be an interesting capture on a moderately slow day.

Have you ever taken some time to look closely at a Mourning Dove? They are lovely, sleek birds, with very soft, pleasing colours. We tend to think of them as just mouse-brown, but they embrace a broader palette than that. For one, there’s the soft blue orbital ring. The blue is actually coloured skin, rather than feathers. Then there’s the pink corners to the mouth, the overall effect as though they’re wearing eyeshadow and lipstick. The male (above) can be told from the female (below) by the blue-gray wash over the back of his head and neck, and the dusty rose across his breast, which the female mostly lacks. (He’s also a bulkier bird than the female, although this usually requires a pair side-by-side to assess easily.) Both sexes sport an iridescent patch on the sides of their necks. Interestingly, the Birds of North America account indicates that males will usually show pink iridescence, while females will have olive-green, “although some pink iridescence occasionally occurs.” Perhaps they got their memos crossed? Pink does seem like a much more feminine colour, anyway.

The Moth and Me #11

The Moth and Me #11 is now up over at Beetles in the Bush. Ted only hosted his first carnival a few months ago, but he’s an old pro at it now. His moth carnival is an excellent installment, taxonomically organized with great additional information about each of the groups highlighted. This month’s edition contains 15 entries from 9 contributors, and is definitely worth a read – you’ll learn something new just from reading through Ted’s post, even before following the links to all the others. Check it out!

TMaM is headed to The Skeptical Moth for the June edition. Send Chris or myself (canadianowlet [at] gmail [dot] com) your submissions by June 13.

Spotted Lady Beetle

Spotted Lady Beetle

A couple posts ago I wrote about Leafy Spurge, and in the header photo there was a beetle on the plant. The beetle is a Spotted Lady Beetle, Coleomegilla maculata, one of our 481 native species of lady beetles. It’s found through most of the east, and is probably the most common lady beetle in our part of the continent. Most lady beetles are predaceous, feeding primarily on aphids but also taking other invertebrates as available. However, Spotted Lady Beetles are somewhat unique in that, because they’re out relatively early in the season, they will supplement their diet with pollen (dandelion is a favourite; another reason to leave them be in your lawn).

Many native lady beetles are slowly declining and disappearing across much of North America. Competition with the introduced Asian Multicolored Lady Beetle is probably a factor in this trend, but the increasing application of pesticides and herbicides to our crops (including our grass crop that most of us maintain around our homes) is probably also part of the reason. The Lost Ladybug Project, organized by the Department of Entomology at Cornell University, is a citizen science project that aims to track the occurrence of our native lady beetles through the submission of photos taken by people like you, allowing ladybugs to be found and tracked from more parts of the continent than if it were just simply Cornell staff going out to look. It’s as easy as looking for ladybugs, taking a photo, and uploading your photo using their online submission form. For more information on participating, or to upload a photo you’ve taken, visit the Lost Ladybug Project’s website. If you’re in Ohio, the Ohio State University runs a similar program for that State: check out the Buckeye Lady Beetle Blitz.

Georgian Prominent

Georgian Prominent, Hyperaeschra georgica

I discovered this moth tucked into the loops of the mistnet at the banding station a couple of days ago. It was tucked underneath on one of the lower loops and I almost missed it as we walked by on our round to check the nets. There are a few species of moth which are regularly encountered during daylight hours, and I had actually been seeing a few of these about, fluttering from spot to spot in a slow, un-butterfly-like manner. This one doesn’t fall into that category, though, and I was surprised, and delighted, to spot it there.

The species is Georgian Prominent, Hyperaeschra georgica. The prominents (family Notodontidae) are all mostly thick-bodied, often fuzzy moths that usually rest with their wings curled around their abdomen or tented over their back such that their shape is raised from the surface they’re resting on (compared to other moths that keep their wings spread and so are flat against the surface). For whatever reason, the prominents are among my favourite groups of moths.

Georgian Prominent, Hyperaeschra georgica

The Georgian is a fairly widespread species, found through most of the continent except the Pacific Northwest. The caterpillars feed on various species of oak, and there’s hardly a corner of the continent that’s without some sort of Quercus species. Around here these moths will be on the wing from around now through mid-summer, though they’ll have a longer flight season in the south of their range.

I gently plucked it from the loop in order to get a better photo, but the contact woke it up and it fluttered from my hand to the ground. After a few more shots, I picked it up and placed it in some shrubs where it would have some protection from birds until night fell.
