Search of the Week: “what can I feed hummingbirds to get them protein”

Sugar water is a substitute for the nectars of hummingbird-pollinated flowers, which provide the birds with energy-rich sugars, water, some electrolyte salts, and little else. Almost everything else their bodies need, including protein, comes from eating insects, spiders, and other small arthropods. (Salvia sp. in my garden, copyright S. L. Williamson)

Hummingbirds do need extra protein in their diets during the nesting and molting seasons. Here are some tips for helping them meet their protein needs:

  • Don’t use broad-spectrum pesticides in your yard: Many common yard and garden pests, including aphids, whiteflies, and various annoying gnats and midges, are just the right size for hummingbirds to eat. Even if the birds don’t sicken and die from eating poisoned prey, spraying pesticides destroys an essential source of natural nutrition and makes your yard less attractive to them. Switch to targeted, low-risk remedies for specific pests, such as a hard spray of water under leaves for aphids and various forms of the natural pest pathogen “Bt” (Bacillus thuringiensis) for caterpillars and mosquitoes. Also, beware of purchasing hummingbird flowers from mainstream garden centers. Many of these plants have been unnecessarily treated with the same neonicotinoid pesticides that have been implicated in the terrifying declines of honeybees, native pollinators, and native insect-eating birds.
  • Cultivate a compost pile: Fruit flies are attracted to decaying vegetable matter, including fruit rinds and scraps. Garden experts often advise against adding fruit to compost piles/bins in part to discourage fruit flies, but these tiny insects provide excellent hummingbird food while aiding the composting process.
  • Grow your own fruit flies: There are lots of recipes on the Web. When a culture matures, just set the container in your garden and open it so the flies can escape.

The one thing you absolutely, positively should never, ever do is add protein supplements to your feeder solution. It’s unnatural, the solution will spoil much faster, and the birds will not like the taste. (Captive hummingbirds drink protein-rich liquid diets, but only because they have no choice. They’d much prefer flower nectar or sugar water for energy and water and a variety of insects and spiders for protein, amino acids, vitamins, minerals, etc.)

Search of the Week: “is sevin powder safe for hummingbirds”

Hummingbirds should be dusted with pollen, not pesticides.

Hummingbirds should be dusted with pollen, not pesticides.

NO! Sevin is an indiscriminate pesticide that’s considered moderately toxic to birds. Even if it doesn’t kill hummingbirds outright, it will kill their prey and deprive them of a vital food source. There are many safer and more targeted solutions available for controlling garden and household pests.

Search of the Week: “what birds are protected in arizona”

Virtually all of them, and most by federal and state law.

The Migratory Bird Treaty Act was enacted to protect America’s native birds, including the elegant Snowy Egret, from commercial exploitation.

Almost all birds native to the United States, whether migratory or not, are protected under the Migratory Bird Treaty Act. This includes songbirds, hummingbirds, woodpeckers, roadrunners, birds of prey, waterfowl, wading birds, shorebirds, seabirds, etc.

State laws can be more restrictive than federal but not less, so the MBTA represents the minimum level of protection for the native birds it covers—and it’s one of the strongest wildlife laws in the world. It was enacted in response to the wholesale slaughter of egrets, herons, and other charismatic birds for the feather trade. (It also put an end to market hunting of native birds, but this came too late to help the Passenger Pigeon.)

The MBTA allows the U.S. Fish & Wildlife Service to issue permits for managed recreational hunting of most traditional prey species, lethal control of “nuisance” birds, and live capture and possession of raptors for falconry (in states where falconry is legal), but commercial exploitation is strictly prohibited. That means you can buy a state hunting license and federal and state “duck stamps” and legally shoot your limit of waterfowl, but you can’t sell them or any part of thereof (including mounted trophies). With some exceptions for migratory gamebirds (including captive-bred ornamental waterfowl and the aforementioned taxidermy), you also can’t keep protected birds in captivity (even for altruistic reasons) or have their feathers, bones, nests, or eggs in your possession without a scientific,  educational, or religious/cultural permit.

Native “upland/nonmigratory gamebirds” —quail, grouse, Wild Turkey, and (in Texas only) Plain Chachalaca—are under state jurisdiction. States often regulate hunting of introduced game species such as pheasants and partridges, but most nonnative species—House Sparrows, European Starlings, Rock (Domestic/Feral) Pigeons, Eurasian Collared-Doves, Indian (Blue) Peafowl, feral chickensferal parrots, escaped (but non-breeding) domestic* or pet birds, etc.—have little or no legal protection anywhere in the U.S. except whatever might be afforded by county or city ordinances (which may have priority over state ordinances).

Disclaimer: IANAL. This is just a brief summary of common situations where the MBTA applies. It’s up to you to read federal, state, and local laws and understand how they apply to your situation. If in doubt, consult the appropriate government agency for advice.

* Special regulations apply to Mallards and Muscovy Ducks, since they exist in the U.S. as both domesticated (captive and feral) and native wild birds.

Search of the Week: “care for feral cats”

Two simple steps:

  1. Trap them. Animal control agencies often have cat-sized traps to loan. Canned cat food and sardines make good baits where you’re not likely to catch a skunk or other wild animal; otherwise, try catnip.
  2. Take them to the nearest shelter that will rehome or permanently house them, or euthanize them if all else fails.

Alternatively, have them neutered and vaccinated and confine them to your own property in a predator- and escape-proof enclosure.

Do not leave them out on their own. Cats are domestic animals, and prolonging their homelessness to the detriment of your neighbors, other pets, and wildlife is almost as irresponsible as abandoning them in the first place.

Salting the earth, oiling the sea

For the last few months life has been an emotional roller coaster. The weather here in southeastern Arizona has been insane. Wildlife and people alike are still hurting from last summer’s drought, despite abundant winter rains that produced a good spring wildflower show and renewed the flow of creeks and rivers. A snowstorm struck the high desert and sky islands at the end of April, during what is usually the peak of spring migration. Seeing Red-faced Warblers and hummingbird nests in the snow was an unforgettable yet heart-wrenching experience.

On the personal front, Tom and I are celebrating the engagement of one of our most cherished friends, but three other friends recently lost battles with cancer (two in one week), and three more are fighting it. Many of our friends, neighbors, and colleagues are still struggling with the effects of the economic downturn, and the picture got bleaker with Arizona’s budget crisis, radical cuts to funding for education, and a tourism boycott spurred by the passage of state legislation promoting racial profiling and banning ethnic studies.

A more distant landscape that we love and the communities that depend on it have been brutalized, perhaps beyond recovery. I’m not trying to make the Deepwater Horizon disaster about me, just saying that as a native Texan who spent many happy days on the Gulf Coast I can empathize with the maelstrom of emotions—grief, rage, helplessness, resignation—that residents of the region are feeling right now.

I have nothing but disgust for the cheerleaders for the oil industry who keep chanting “drill, baby, drill” and “jobs, jobs, jobs” in the face of this tragedy. Human lives have been lost. Millions of animals and plants, parts of a natural cornucopia of marine and estuarine ecosystems, are doomed. Traditional ways of life and the communities that depend on them have been devastated. That’s far too high a price to pay for the illusions of energy independence and economic security.

It occurred to me that the oil companies and other huge industries stand to win big from this disaster beyond a short-term spike in oil prices. With the poisoning of the Gulf’s ecosystems, thousands of residents who for generations have fed their families directly from the bounty of the coastal wetlands and the sea suddenly have no jobs, no money to buy food, few immediate alternatives, and little hope for the future. The tourism industry that struggled to recover after Hurricane Katrina was dealt another brutal blow, leaving even fewer options for small businesses and the people they employ. Families and communities will be strained to the breaking point and beyond, as they were in the aftermath of the Exxon Valdez.

Into this economic vacuum and social chaos step BP, TransOcean, Halliburton, and their ilk. Having figuratively sown the earth with salt, destroying the fertility of the Gulf and the traditional livelihoods of its people, they’ve created an employers’ paradise now and for the foreseeable future. These companies and other corporate giants will have cornered the Gulf Coast job market. It’s already started, with BP offering to hire out-of-work fishing boats for cleanup work. What’s to stop them from controlling the entire economy of coastal communities, turning once proudly independent Americans into wage slaves?

Part of me wants to see all the U.S. assets of BP, its partners Anadarko and Mitsui & Co., and its contractors TransOcean and Halliburton seized and turned over to a trust to fund ongoing cleanup of the Gulf, restoration of wildlife habitat, rehabilitation of oiled wildlife, and support of communities whose traditional economic base has been obliterated.

Of course, it would be a huge mistake to tie the welfare of the Gulf and its people to continued exploitation of offshore oil. That’s what led us to this awful situation in the first place. Think about all the people who have had so little to say about the disaster because they depend on the petroleum industry for their income. This isn’t just employees of the oil companies and/or the contractors that serve them. It’s conservationists, too.

Members of the oil and gas industry are major contributors to conservation organizations such as TNC, Conservation International, and the Sierra Club. In return for the millions they donate to these organizations, the companies get photo ops and fake awards to dress up their ads and annual reports, putting on pretty “green” masks to distract their shareholders and the general public from the damage they’re doing to the environment.

Even the promising Teaming with Wildlife proposal was hijacked by oil interests. The original bill would have emulated the highly successful Pittman-Robertson Act and Dingell-Johnson Act, establishing modest federal taxes on wildlife-related merchandise (bird feeders, field guides, camping equipment, cameras, etc.) to fund nongame conservation and watchable wildlife programs. TWW had widespread support from the public, manufacturers, and retailers, but because “tax” is a four-letter word in some circles oil-friendly members of Congress cut a deal to fund wildlife programs with revenues from offshore oil leases. Conservationists were forced to accept a Faustian bargain that is now coming back to haunt us.

Yes, the deep pockets of the oil companies are tempting, but the costs are just too high. Thankfully, there are a few politicians who understand this and are willing to take a stand against the formidable petroleum lobby. California Governor Arnold Schwarzenegger, who had previously proposed expanding offshore drilling to put desperately needed revenues into state coffers, said, “You turn on the television and see this enormous disaster, you say to yourself, ‘Why would we want to take on that kind of risk?'” (Why indeed. Perhaps President Obama would like to answer that question.) “If I have a choice to make up $100 million and what I see in Gulf of Mexico, I’d rather find a way to make up that $100 million.”

I like to think that Gov. Schwarzenegger would come to the same conclusion even if the coastlines of his state were inhabited by working people of modest means instead of rich celebrities. Here’s hoping that other governors and the President follow his example.

More species protected under the Migratory Bird Treaty Act

Recent changes to the Migratory Bird Treaty Act extend protection to over 120 new (non-split) species, some of which have waited decades for legal recognition. Most are vagrants such as Stygian Owl, Flame-colored Tanager, Blue Mockingbird, Cinnamon Hummingbird, Xantus’s Hummingbird, Bumblebee Hummingbird, and Green-breasted Mango that will finally enjoy the same protection under the MBTA as other naturally occurring species. (You hear that, Brookfield Zoo?)

One controversial addition to the list is Muscovy Duck, a neotropical native that has established populations in southern Texas. The problem is with feral and released domestic Muscovies, which are causing a variety of problems. Not surprisingly, duck fanciers are up in arms over a proposal to outlaw breeding of Muscovies except for meat, and I can sympathize. Though the proposal specifically exempts any live ducks in one’s possession prior to the date the rule goes into effect, it will eliminate breeding of highly domesticated strains of Muscovy for show or pet purposes. Apparently, many of those pets are being abandoned where they become nuisances to people,  reservoirs for disease, and competitors for resources with native species, but the bigger problem would seem to be breeding of semi-wild, flight-capable Muscovies to be released for canned hunts. It will be interesting to see how this plays out and whether duck fanciers can work out some reasonable exemptions.
