July, as all northern hemisphere birders appreciate, is the month when the egg timer flips and everything starts pouring back out again in a steady stream south. Adults moving into winter plumage show no such dark markings (as above with Black-headed Gull behind for comparison) but note the distinctive dark-banded bill with yellowish tip.

and a visit to Big Egg Marsh (one year bird!) Then, lucky me, the Tundra Swan got out of the water and onto the ice near a Mute Swan for some nice side-by-side size comparisons. I was psyched to see the one that had been reported but first I had to do some other birding on Sunday morning to keep my year list moving along.

Using ministerial connections he obtained 100 mallard eggs from the US and began to breed and distribute them. It’s a very unfair comparison, but it can be hard to explain, in layman’s terms, what is being lost. Female Mallard, photo by Corey. There the matter may have remained, but for a gentleman named Cecil Whitney.

They breed in dense colonies, incubate their single egg on the feet, and take more than a year to fledge a chick. There are 450,000 pairs of King Penguins in South Georgia, they are thankfully not threatened, and if you can’t go there to see them, then you must see these photos.

Did you know for example that some species of bee are cleptoparasites , exploiting the nests of other species for their own eggs. Finding that certain species have a “Dark Queen” only served to fuel the comparison. The preface opened my eyes to the wonderful world of bees and had me gagging for answers.

Most interesting for me was the mental lock most people have that we vegans are always looking to break or find the key to: Why do good people who understand what happens to animals for unnecessary products such as “steak” or eggs, continue to consume such things? The answer, throughout the entire 300 pages, essentially is: Because they do.

I had hoped to have some Semipalmated Plover chick photos for comparison but as of last night they seem to be still at the egg stage. This is a photo from last year, as neither the Pacific nor the Red-throated Loons ‘ eggs have hatched yet, it’ll be about 2 more weeks. Ahh, that’s why. With some serious legs.

The chicks need six months to develop so the adults lay their eggs in January. In comparison, over 15 thousand Griffons make the same crossing each season. The south, just 21 kilometers away, is the coast of Morocco and the Griffons have just completed a short but arduous sea-crossing across the Strait of Gibraltar.

Let us start with a comparison of size. With only 3-5 eggs per breeding attempt, it is less productive than the European Robin with its 4-7 eggs. For those serious about robins, the choice will most likely come down to either the European Robin or the Japanese Robin. A European Robin. A Japanese Robin.

About three billion birds fly north to the Boreal Forest each spring to build nests and lay eggs. By comparison, 27 to 58 kilograms of carbon dioxide are emitted in the conventional production of a barrel of crude oil 3. For many waterfowl, this area is their only nesting ground 2.

Both Elk and songbirds have the same basic method of inseminating eggs, which is one of the steps in reproduction (but not by any means the first!), Songbirds grow the offspring internally for only a very short while, and then pop out an egg, which is then cared for over a significant period of time until it hatches.

Each plate is signed with the artist’s initials, which makes for an interesting exercise in comparison. Some offer nest information, egg information, breeding timeline, in flight views, etc. It’s a tough comparison. Each offers something different & you do feel that one guide does not cover everything at all!”

If the male’s color fades after the first egg, the female reacts by laying a smaller second egg – seemingly deciding that it is better to cut her losses as the male apparently is the avian equivalent of a deadbeat father. The smallest on offer is the Rufous Piculet (8-9.5

If this comparison bothers you, here’s something to comfort you (but not me): Donald Trump will be the next US president, the squirrel will not. I leave it to you, dear valued reader, to decide whether the scientific or the common name is more fitting. A giant squirrel, actually.

Fortunately for the buntings, they seem to detect most cuckoo eggs smuggled in (75% in one study). A study found that for Plain Prinia , egg characteristics in a mainland China location with many cuckoos make it much easier to spot cuckoo eggs than in a Taiwan location with few cuckoos ( source ). Better safe than sorry.

The Large-billed Crow ( video ) is one of the natural enemies – in the study above, it predated 19 eggs from four pitta nests. The Lesser Coucal resents the comparison with parasitic cuckoos – it admits that as a fellow cuckoo species, it is related to them but takes care to bring up its chicks on its own.
