According to the web and book sources I'm looking at, female yellow-rumped warblers lay 4 or 5 eggs and incubate them for up to 13 days. The eggs are laid in a nest typically made up of moss, strips of bark, and grass. The nest itself is usually in a coniferous tree.
ALL birds lay eggs (that is, the females do) No bird gives birth to live young.
They may eat the eggs or young birds if left unattended.
By eating food/ drinking water contaminated with worm eggs or young worms.
A Blue Jays egg is a pale bluish green color
The moth lays its eggs in the flesh of the cactus, which the young eat and destroy as they grow.
They would if they could catch them, but they would probably eat young or eggs, as bears will eat almost anything organic.
Most commenly, the Canada Warbler has a clutch of about 3 to 5 eggs.
A parasitic relationship. The cucko lays its eggs in a warbler (E.g Reed warbler)
When a reed warbler makes its nest and lays its eggs, a cuckoo later comes to lay HER eggs in the warbler's nest while the parent warbler is away. The cuckoo does this so that the warbler can take care of the her chick instead. The warbler takes absolutely no notice of what's happened and takes care of her eggs. When the cuckoo chick has hatched, it usually pushes away the rest of the chicks and eggs out of the nest so that it has a survival advantage. So the parent warbler usually ends up losing all of her eggs and raising one cuckoo chick even after the chick has grown 3 times as big as the warbler.
The Kirtland warbler's eggs are cream colored which are speckled with brown. The eggs are typically laid in a number of either four or five.
a warbler provides a cuckoo with a nest to hold its eggs. it also provides a cuckoo with food.
The cuckoo is a parasitic bird (with only a few exceptions), meaning it relies on other birds to nurture its chicks. So the relationship between a cuckoo and a warbler is that the cuckoo lays one of its eggs in the warbler's nest and the warbler ends up raising a cuckoo chick.
A parasitic relationship. The Cuckoo lays its egg in a warblers (E.g. Reed warbler) nest and the cuckoo hatch-ling expels the eggs of the warbler. Therefore one species (the Cuckoo) benefits and the other one is at a disadvantage (the warbler). So the symbiotic relationship is parasitic.
Feeding together would probablybe a better description of their association. While cattle (or other large, grazing animals) are grazing, insects and other preys are disturbed, making it easier for the cattle egret to catch them. Cattle egrets are feeding on grasshoppers, crickets, flies, moths, spiders, frogs, earthworms. More info on cattle egret could be found on http://en.wikipedia.org/wiki/Cattle_Egret
The northern cardinal and the brown-headed cowbird have a symbiotic relationship. The brown-headed cowbird lays its eggs in the cardinal's nest (and in the nests of other species, too, such as the yellow warbler). This harms the cardinal's chances to reproduce. It's a parasitic relationship.
Many reptiles lay bright yellow eggs. Yellow eggs are often a sign of the eggs not being fertilized so many reptiles have this capability.
You can tell by the materials used, the shaping and even the eggs that are in the nest. e.g. a cape warbler has a spherical nest that's weaved with grass and has white eggs with brown speckles
What you want are the Golden eggs.
