From Hiro, we learn how Northern Pygmy Owls are “rule breakers,” not incubating eggs till all are hatched and then raising owlets that mature at the same rate even though the eggs were laid asynchronously (as most owl eggs are). It’s a lot of work.

As you can easily judge from the dullness of this information, it is not something I made up but rather an appalling example of nepotism in the naming of birds. Sir James McGrigor (1771-1858) Director Gen. of Army Medical Department 1815-1851.

In some cases, for example Jabiru, the information is tucked away at the end and can’t even be discerned from the range map. Plate 28 from Audubon Bird Guide, Eastern Land Birds, by Richard H.

There are thousands of shorebirds that visit Broome each year and the majority of them are now in the northern hemisphere hopefully sitting on eggs. Not all of our shorebird species migrate and those that reside here are also currently sitting on eggs, or thinking about laying eggs in the upcoming weeks.

For example, in the Delaware Bay, warming coastal waters can cause horseshoe crabs to lay their eggs earlier than normal; conversely, more intense and frequent coastal storms can cause late spawning. In both cases, knots, which feed on the crabs’ eggs, can miss their peak refueling opportunity. Birds in Delaware Bay.

Superb Starlings avoid this when using helpers, much like rich people presumably reducing the stress of raising kids by hiring a couple of nannies. She also laid eggs in Melba Finch nests. But that is the environment they survive in, get grants, get professorships, etc. Red-billed Firefinch.

You’re a mammal, so you might be tempted to use yourself as an example mammal, but humans are actually kind of bad examples of mammals, so perhaps we’ll use a well studied hoofed animal instead. Think about the difference between birds and mammals. as both use internal fertilization. All the nurturing has to come from mom.

A few families have a small number of eggs in the clutches, like gulls or cormorants. Others, like the petrels and some of the auks, will lay a single egg per breeding attempt. Unique among the auks, indeed among seabirds, they will attempt to double brood, to lay another clutch after successfully raising the first chick.

This week at 10,000 Birds, it’s all about how birds get around to bumping uglies (I’m talking about cloacas here), who they do it with, and how this actually leads to raising chicks…the birds and the bees of birds, you might say. Other infamous brood parasites include cowbirds and Old World cuckoos.

As a Northeast birder I am familiar with the alarming decrease in the number of Red Knots along Atlantic shores and have signed petitions and written e-mails calling for legislation and rules that will limit the overharvesting of the horseshoe crab, whose eggs Red Knots depend on. million in the late 1990’s.

For example, a government might refuse to protect - or even willfully destroy - its own natural treasure, as when, in the 1990s, Saddam Hussein's regime drained the wetlands that were home to the persecuted Marsh Arabs. In Nicaragua, the army patrols beaches to protect sea turtle eggs.

A vegetarian of the first sort has no grounds for objecting to the eating of animals—molluscs for example—too rudimentary in their development to feel pain. Nor could he object to meat-eating if the slaughter were completely painless and the raising of animals at least as comfortable as life in the wild.

Animals raised for food suffer miserably. The overwhelming passage in November of Proposition 2 in California, which banned tight confinement of many of the animals raised for food, is a fine example of the power of publicity to educate people about the atrocities we commit to those animals who have no voice of their own.

Here is an example: I think I saw a Red-tailed Pennant, Brachymesia Furcata, two weeks ago in the Florida Keys; that’s my photo above. The Natural History section points out that Red-tailed Pennants hold their wings flat or slightly lowered, while the skimmers tend to raise their wings. With odonates, there are always exceptions!

The last example suggests the difficulty of making a clear distinction between an animal part and an animal product. If a genetically engineered animal’s legs periodically fell off, would not its legs be more like a product of an animal (analogous to eggs) than a part of the animal? Would the blood be analogous to milk or eggs?

How do I know of their Gothic moods when they have hidden them so well in an egg-white shell of conformity? Here are a few examples from my picture archives: Black-headed Gulls – or Black-haired Gulls? It is the claws that give them away, their black nail polish. As a matter of fact, all the gulls I checked had black nails.

For example, we will not claim that Martin is opposed to moral vegetarianism because he likes to eat meat without a guilty conscience. The contrast would be, for example, “health vegetarianism.” First, I will raise some questions that usually are not asked, let alone answered, by moral vegetarians. Each argument has an audience.
