but lays one pointy blue-green egg each year on the flat mossy branch of a redwood.
the egg-sucking chick-eating Steller's jay. About 4000 murrelets remain in California with about 300 to 600 in central California's Santa cruz Mountains.
Squirrels ravens and owls also swipe murrelet eggs but jays are the biggest thieves in California gobbling up 80 percent of each year's brood.
Unless more eggs survive the central California population will go extinct within a century according to a 2010 study published in the journal Biological Conservation.
The two-pronged approach will teach the black-crested jays to avoid murrelet eggs on pain of puking.
and California least terns the jays eat their eggs too. Steller's jays don't seek out murrelet eggs.
But when the birds circle picnic areas near murrelet nests some discover the chicken-size eggs make a fine treat.
The smart savvy birds will return to the same spot over and over searching for food. Murrelets to their misfortune nest in the same tree every year.
Watch the mysterious marbled murrelet For an animal that lives for some 20 years losing an egg is a terrible terrible loss Bensen said.
World's worst Easter egg hunt The plan the brainchild of Humboldt State graduate student Pia Gabriel centers on carbachol an odorless tasteless chemical that provokes vomiting with just a small swallow.
Small chicken eggs dyed blue-green and speckled with brown paint were offered as meals to jays with carbachol hidden inside.
Wild Steller's jays in this first treatment group usually tried just one taste of the carbachol-filled fake eggs.
The quick action helps the jays link the eggs with the illness. Some jays wouldn't even touch the eggs evidence that murrelet egg-nabbing is learned a behavior Golightly said.
In spring 2010 and spring 2011 a team zip-tied hundreds of the copycat eggs to redwood-tree branches in several parks.
Each chicken egg was colored painstakingly (Benjamin Moore Oceanfront 660) and speckled to resemble murrelet eggs.
A control batch of red speckled eggs also decorated the forest. We've been accused of being the Easter bunny in the woods Golightly told Ouramazingplanet.
A second wave of eggs set out a few weeks later measured whether wild jays learned to avoid tossing their lunch.
The mimic eggs reduced egg-snatching by anywhere from 37 percent to more than 70 percent depending on where the eggs were deployed.
For instance one spot lost eggs to bears so not as many jays got to sample the carbachol.
The bogus eggs were set low on branches to avoid drawing jays toward real murrelet eggs.
A retched success The tests were so successful that Halbert applied for oil-spill restoration funds to start training Steller's jays in the state parks.
In spring 2012 during murrelet nesting season researchers spread hundreds of vomit-inducing eggs throughout Butano State Park and Portola Redwoods Park in the Santa cruz Mountains.
We've found a significant decrease in predations by jays the number of times eggs get broken she said.
The effects were monitored with camera traps and a second wave of mimic eggs. Reducing predation on murrelet nests by 40 percent to 70 percent would stabilize the Santa cruz Mountains murrelet population according to the 2010 study published in the journal Biological Conservation.
In 2012 the smallest cutback in egg attacks by Steller's jays and other predators was 44 percent
and avoid those rare blue-green eggs that made them retch. Nothing else in the forest looks like a murrelet egg.
If taste-aversion training were to spread through the murrelet's range it would not be the first time a bird would require human babysitters to survive think of condors who need devoted monitoring and care..
But Halbert said all the efforts to stop egg-stealing won't matter if the parks can't shrink the jay population by getting rid of their campground crumb food source.
While Redwood National park is going oecrumb clean the park will wait on the vomit eggs Bensen said.
They typically lay several egg sacs and cover them in webbing for protection. Funnel spiders lay eggs in the fall

The cells containing the passenger pigeon DNA could be transformed into cells that produce eggs and sperm

#Quail Moms Customize Their Egg Camouflage Quail eggs are like fingerprints a new study suggests.
The creamy blue-and-brown speckled eggs splashed like a toddler's art project vary among birds
What's more in a laboratory experiment quail camouflaged their eggs according to their personal pattern picking lighter sand for less-speckled eggs and darker sand for eggs with more brown splotches.
What surprised researchers was the discovery that quail changed their approach to camouflage as their eggs got darker.
It's as if they knew the characteristics of their own eggs and chose the best substrate with
and their eggs need good hiding places. In the experiment quail could lay clutches in sand with white yellow red or black hues.
Researchers photographed each spot where the quail laid eggs and each location they ignored. The images revealed
More than 50 percent of the time quail chose the sand color offering the best or second-best protection for their own egg pattern the study found.
The amazing thing is this change in strategy for the different eggs Lovell said. Quail with the creamiest egg colors picked white or yellow sand.
This strategy called background matching aims to hide the eggs by blending into a similarly-colored background.
Quail with darker more splotchy eggs conceal their eggs not by matching a background color
but by trying to break up the egg's outline through its color pattern an approach called disruptive coloration.
The same strategy the military uses in its camouflage patterning the egg splotches disrupt its own outline with the colors
and patterns on its shell Lovell explained. What the spots seem to be doing it making a predator think an egg is different from an egg shape he said.
Seeing splotches The quail were raised in captivity at the University of Glasgow in Scotland and had seen their eggs before the experiment started.
 It's possible that they learn the patterning through seeing eggs that they've laid Lovell said.
In the wild there is some evidence that birds are often less successful with their first clutch of eggs.
It may be that at that point in time they're not able to select the best place to lay their eggs.
Scientists think birds use patterning on eggs for camouflage but the darker colors may also help strengthen weak spots
or regulate temperature Lovell said. The shell color comes from two pigments: blue-green biliverdin and red-brown protoporphyrin which are both breakdown products of hemoglobin (the oxygen-carrying protein found in the red blood cells of all vertebrates.

#Why Aren't Turkey Eggs Sold at the Grocery? As you pick up your turkey at the grocery store this week you might wonder why you never see the birds'eggs for sale.
Gobbling turkeys do lay eggs. But selling them in grocery stores would have its drawbacks. Turkey eggs small numbers and big size make them less practical for the poultry section.
Chickens start reproducing early and pump out more eggs than turkeys. The larger size of turkey eggs requires more room to nest
which takes up too much space in a coop. Economically meat from a grown turkey bird is much more valuable than an extra large fried egg.
Plus some breeds of turkey have retained a strong mothering instinct which is good for hatching chicks
but tough on farmers trying to collect the eggs. If you still want turkey eggs your best bet is to try a farm stand.

#Did'Deadly'Spider Eggs Really Hitch a Ride on Imported Bananas? It's enough to make you do a double take the next time you unpack your groceries!
A woman in Essex England recently discovered that a bunch of bananas delivered to her home by a local grocer was infested with spider eggs.
and reportedly identified the eggs as those belonging to the immense and deadly Brazilian wandering spider according to MSN New zealand.
It's unlikely that the woman's bananas were infested truly with deadly spider eggs said Richard Vetter a retired research associate of entomology at the University of California Riverside.
(if there even was had a spider laid the enigmatic eggs. Egg sacks are much harder to identify than spiders.
To identify them you need familiarity with the spider first then the egg sack Vetter said.
It's unlikely that British exterminators would be intimately familiar with the egg sacks of spiders from South and Central america he added.
However it is possible that the eggs in question belonged to an arachnid Vetter said. There are several genera of spider that sometimes survive the long trip from banana-producing nations such as Brazil Mexico Nicaragua and Costa rica to other parts of the world.
Among them are Phoneutria and Cupiennius two types of spiders that are commonly known as wandering spiders.
