For the Birds

Birds and windows don’t mix. When they come into contact with one another, the bird is usually the looser. Glass reflects the outdoors and birds see the glass as a place to fly through. Research now suggests that in the United States, 1 billion birds die each year due to window strikes. Even when a bird flies away after a strike, it’s estimated that upwards of 60% die within a 24 hour period. This information comes from wildlife rescue organizations’ records of birds brought in for treatment after window collisions.

The numbers are daunting and birds are dying. We human types can mitigate some of that problem by using window decals in the forms of lines, dots, or cutesy decorations.

I’ve opted for cutsey in my window situations.

Decals are easy to put on windows, available through many sources, and last quite a long time. In my own experience, my back garden windows are the main source of bird collisions, obviously because of the feeders. For some years now, I’ve placed decals on those particular windows (I’ll talk about other window remedies later). While I love the aesthetic of a clean, large window, dead or dying birds because of those windows is a non-starter for me. I’ll tolerate some interruption of that sheet of beautiful glass for the sake of even more beautiful birds. I’ve grown used to the decals; they don’t hinder my inside enjoyment of the outside and it’s now a rare event that a bird hits my windows.

This window is in in my living room, the photo taken from outside. It’s easy to see how a bird might think it can fly right through. It’s been 4 years since a bird hit this window; sadly, it was a beautiful Cedar Waxwing. In addition to the decals placed at the bottom half of the window placed a few inches apart, there is an indoor blind hanging in the upper half with slats partially open so that the horizontal slats indicate to birds that the window isn’t a flyway.

When we were in Costa Rica, a number of the places we visited opted for vertical lines on the windows. Some newer buildings are using glass that has dots or lines formed in the glass. Decals, lines drawn on glass with oil-based paint markers, blinds (vertical or horizontal), patterned draperies–anything that disrupts a reflection of a natural landscape is a cue to birds that the window shouldn’t be part of the bird’s flyway. I’ve witness a hawk, and many migratory and resident birds fly towards my windows, to suddenly bank away as they clearly recognized that the path isn’t safe. What they think the window is at that point I have no idea, but that the birds didn’t head straight into the window is a win for the birds. For me, that alone is worth a few in-the-way-decals.

Most of my windows have blinds on the inside and because there are lines, the birds see that those windows are not through-ways. When I raise the blinds, I’ve placed a few decals on the lower part of the windows so that the birds don’t hit the glass.

Squirrel and Pecan

I watched this annoying cutie as he munched a treat of a whole pecan. Though he chose to dine in the small Red Oak tree standing in my front garden, he snatched the pecan from some other place, as only oaks with acorns live here. The oaks are stingy with acorns this year; there are fewer than normal, probably due to drought. However, it’s clear that a neighboring pecan tree is producing some yummy fruits.

Squirrel kept an eye on me, wary that I might be after his pecan.

Squirrel and I have in common a love of pecans. For me: fresh and raw, roasted in salads, added to cakes, pies, cookies, and ice cream. For squirrel, right out of the hard shell, balancing on a limb while nibbling.

Don’t fret Squirrel, I’m not after your snack, I have my own delectable pecan treat to enjoy in a few days.

I enjoyed and learned something new from this story on NPR last November about the history of and proper pronunciation for the word ‘pecan’.https://www.npr.org/2024/11/27/nx-s1-5205291/you-might-be-surprised-to-hear-how-the-word-pecan-is-supposed-to-be-pronounced

Three Bees Pollinating

Spring sprung many months ago, summer’s hardy floral gifts, amidst Texas heat and drought, delivered color and life with attending pollinator action throughout those toasty months. Summer is finally done and autumn is a robust flowering period, full of blooming goodness. A pollinator frenzy is in full swing in my Austin garden.

The yellows, especially Plateau Goldeneye, Viguiera dentata, are the pollinators’ delight. Monarchs have mostly drifted southward along gusts delivered by the last cold front. Other butterflies seem to be on vacation, but bees are still around and about–and pollinating. Most folks know about honeybees, but native or wild bees, are common and vital in any healthy ecosystem, whether in a natural green space or a planned and loved garden. In a recent stroll through my garden, I observed multiples of three kinds of bees that were all-in with their pollination business, sharing flower space they buzzed about a Plateau Goldeneye.

Here, a honeybee works the flower, her little leg splayed out, maybe for balance or perhaps preparing to scoot over to the next flower. A bee’s version of getting a leg up?

The same bee on the same flower, all hunched up and nectaring away!

This bee isn’t a honey, but a native, or wild, bee. My best guess, utilizing this website hosted by an entomologist at The University of Texas whose research focuses on native bees, is that this little gal belongs to the leafcutter bee family.

I like this bird’s-eye view of the leafcutter bee, pollen pantaloons (aka, corbiculae) full-to-bursting with a packed load of beautiful, golden pollen.

The third bee sort zipping around was this tiny thing, most likely a native sweat bee. All native bees are efficient pollinators, regardless of size, though size dictates how much nectar is consumed and the amount of pollen that is gathered. This little one won’t sip as much nectar or pack as much pollen as her bumble relatives, but she and her sisters are excellent in their important work.

This shot captures the difference in size between the sweat and the honey bee. Both are focused on their respective flowers.

Some bees are generalists, visiting a variety of flowers, others are more particular, arriving when certain flowers are in bloom, absent from the garden when that plant is in a resting stage. How the bee knows when its favored bloom is ready for pollination is a mystery, at least to me. Entomologists understand much about honeybees, but there’s comparatively little research on native bees. There are roughly 20,000 native bee species in the world, about 4000 reside in North America, and 350 in Texas. In fact, a new bee was recently discovered and named, existing only in Texas and Oklahoma: the Andrena androfovea–a blue bee, which you can read about here. This blue bee is one of those bees that sips from only one species of plant!

I’ve “identified” roughly 15-18 native in my garden over the years. I don’t necessarily know the name of each (though I know some), as there’s not much information available, so I look at photos and make guesses. Lots of guesses. But I have learned to recognize a bumble from a carpenter, a sweat from a leafcutter, a metallic from a bee mimic. I’ve become familiar with their habits: some are wood nesters, others nest in the ground, most (except for honeybees) are solitary and make small amounts of honey to feed their offspring. I recognize the leaf ‘damage’ that bees do to certain plants in my garden, as they pack their nesting sites with leaf matter, mud, and pollen. Some native bees forage for a brief time in early spring , lay their eggs in protected wood or plant stems, then die. Others are around throughout the growing season, procreating and nectaring all the while.

Native plants and native wildlife, insects included, evolved together and need each other to survive. A vibrant ecosystem will support this symbiotic relationship which defines the life cycles and relationships of flora and fauna. Go native and watch your garden and its inhabitants bloom with life and activity!
