An Invitation to Hummingbirds

Broadtail Hummingbird_COS_LAH 780My yard is full of hummingbirds! Last summer I faithfully put out feeders full of sugar water, but had no takers. Not a single one. The only hummer that visited was a Broad-tailed Hummingbird that stopped by to check out the lone flower on a honeysuckle vine that was sitting in its can, waiting to be planted. But this year! From mid-July to late August, I probably had over a dozen in the yard at any one time—Broad-tailed, Rufous, and even several Calliope Hummingbirds that hung around for over a week. It was all I could do to keep my two feeders filled.

Checklist Changes

Yellow-rumped Warbler- Myrtle's_Patagonia-AZ_LAH_3751Many serious birders keep a life list of the bird species they’ve seen. We can tell you exactly how many birds are on that list, and there’s great excitement when we can add a new “lifer.” We may also have a list of “target birds,” those not yet seen, and we often spend considerable effort tracking them down. But once a year, we have an opportunity to add a new bird or two without lifting a finger.

All year, ornithologists are busy debating bird taxonomy. They present evidence—behavioral, morphological, a new DNA analysis, etc.—to support their opinions as to which species need to be split into two, which need to be lumped together as one (perhaps as subspecies), which need to be moved to a different genus, and other taxonomic changes. Every July, the AOS (American Ornithological Society) publishes the agreed-upon changes, and we all scramble to update our life lists.

Birding Down Under: Queensland Excursions

wongabelnp-qld-australia_lah_3794Tropical rainforests. That was why we had come to northeastern Queensland. I had romantic visions of colorful birds, stunning flowers, perhaps a python or two. Now that we were finally there, it was time to see if my fantasies had any basis in fact.

Our first excursion was to Eubanangee Swamp National Park, south of Cairns. The terrain was rolling grasslands and scrub interspersed with tracts of forest, mostly in the valleys. Cloud-shrouded mountains loomed in the distance. I figured that the edge habitat would be an excellent place to find birds, but the trails were so dark and the foliage was so dense, I was quickly frustrated. Clearly, I need to work on my “birding by ear” skills!

Cool Birds

1991-08 Karin & Teri in sprinklersAs my grandmother always said, “Horses sweat. Men perspire. Women glow.” How do we avoid this sticky situation? Kids run through sprinklers and adults head for the air conditioning, but what do the birds do when the thermometer climbs? They don’t sweat they can’t take advantage of the A/C. However, that doesn’t mean they just sit there and bake, either.

Because birds have relatively high body temperatures—a Golden Kinglet’s temperature was measured at 111° F!—it’s critical that they avoid getting too warm. Many essential proteins begin to break down at temperatures just a few degrees higher, so overheating could easily be fatal. Thankfully, birds have all sorts of ways of beating the heat.
