Synopsis: 4.4. animals: Other: Nest:

Many chicks intentionally abandon the nests in which they hatched to seek out temporary or full adoption by foster parents.

This nest switching has been seen in seabirds like gulls and terns as well as storks, raptors, egrets and herons.

If they moved into nests containing fewer or younger chicks than their previous homes, then they could also receive more food by more easily outcompeting smaller adoptive siblings.

But why would the adoptive parents allow the intruder into their nest especially to the detriment of their own young?

Nest invasions are common, but unlike for white storks, there is a significant cost incurred by the foster parents:

White storks allow baby intruders to share their nest and food-but why?(Thinkstock) Given such high risks for adoption, why hasn't evolution endowed these birds with a better ability to identify oe and reject oe intruders?

selection will favour universal acceptance of young in the nest. In other words, it may be better to needlessly waste resources on alien infiltrators than to accidentally reject one of your own hatchlings.

they preferred cotton previously used by other mice to unused cotton for nest-building. Perhaps most surprising the mice even preferred parasitised cotton balls to clean ones.

When a desert ant leaves its nest in search of food, it has an important task:

These bees, called nest scouts, are on average 3. 4 times more likely than their peers to also become food scouts, the researchers found.

These range from smart self-adjusting thermostats like Nest to IP connected appliances that self-report maintenance information.

The birds nest in tree hollows that are favoured also by species introduced to Tasmania-such as the European Starling

These nests found by Stephen T. Hasiotis and his team from the University of Colorado are at least 207 million years old.

#Fighting to Save an Endangered Bird With Vomit A psychological warfare program centered on vomit could help save the marbled murrelet an endangered seabird that nests in California's old-growth redwood forests.

The seabird doesn't actually build a nest instead choosing a flat branch covered in cozy moss and needles with cover to hide from airborne predators.

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.

These social caterpillars spin large communal white silk nests which are highly visible making them potential targets of surveys via Google street view.

The researchers analyzed data regarding the presence or absence of caterpillar nests collected in these blocks through either direct observation in the field or Google street view.

and thus less chance to properly spot these caterpillar nests. This effect may be less of a problem in the future as Google street view's coverage expands.

#Male Birds Like Nice Nests (ISNS)--One bird species may have advice on how to get its dads to take a more active role in parenting:

Female blue tits that construct bigger nests and decorate them with fragrant plants have male partners that are more willing to invest in raising chicks Spanish researchers report in the journal Behavioral Ecology.

It s an interaction between sexes. oe Different bird species divide the work of building nests in different ways.

 Female blue tits work alone to build nests although males may add feathers later on. That means the nest may provide a window to the female's health.

After spring mating female blue tits collect moss and grass to construct the base of their nests inside the hollows of trees

or artificial nesting boxes. Females then line those nests with soft hair wool or feathers.

Fit females can also search for hard-to-find plants like mint lavender and rosemary to spruce up the homes for their future nestlings.

A haggard female would probably produce a pretty pitiful nest said Montgomerie. After the female finishes the nest both sexes feed

and defend the young. The effort devoted by males is very important in the success of the females

s and his colleagues at Madrid's Museo Nacional de Ciencias Naturales made some nests smaller and added grass

or removed odorous plants from different nests. Â The researchers found that these features influence the care a male will put into the nestlings

I know of that looks at nest traits themselves and how the male responds said Montgomerie.

 At larger nests and those with strongly scented plants males were more likely to be bolder

when there was danger--than males at smaller nests or those lacking the plants the study reported.

s believes in part that males who take more risks may be more willing to defend a nest against predators.

whether a male entered the nest first waited for the female to enter as signal that the coast was clear

or didn t enter the nest at all. Tomã¡s and his colleagues used the risk-taking figure to estimate how much the males imperiled themselves in caring for their young. oetaking the average of a bunch of subjective measures is never a good way to estimate something oe said Montgomerie who hopes that the team will follow up with a more detailed

s is interested in exploring more features of nests built by female birds and the signals they may send to males. oepeople thought that its only function was to form a receptacle for the eggs he said.

But he believes the nests may reveal a lot of information about the bird that built it.

The larger size of turkey eggs requires more room to nest which takes up too much space in a coop.

Each spring Red-faced Warblers along with two other related species the Orange-crowned Warbler and Virginia s Warbler build cupped nests of grass tucked into the ground at the base of trees.

and raise their young until they grow big enough to leave the nest. In the past the three warbler species did not choose the same kind of nest sites.

and are forced increasingly to nest in sites similar to those of the Red-faced Warbler. Â So why does this matter?

Well nest-site choices have consequences for nest survival and subsequent population numbers. When the birds divvied up their use of the different nest sites in the past predation on their eggs

and nestlings by squirrels and mice was lower. But now that the forest has changed and the birds are nesting in similar sites their nests are being detected more often by predators

which means fewer nests are fledging young. Fewer young can then lead to population declines.

It is not entirely clear why nest predation increases when nest sites become more similar over time.

The forest is changing but there is no indication that predator numbers are going up so that s an unlikely reason.

Focusing on finding just one type of nest might be easier than learning to recognize

and search for lots of different nest types in the same way that finding Waldo is easier

but the hard part was finding the nest sites and the foraging sites to include in the study that part took years Slaght said.

One of the reasons it's so hard to find fish owl nest trees is that the birds are almost unbelievably shy.

That means it is very difficult to find nest trees or foraging sites because you almost never see the owls at those locations.

The biologists occasionally find eggs from other species such as terns in avocet nests Hartman said.

When a pair of ospreys bonds they will attempt to mate more than 160 times over a period of weeks resulting in a clutch of two to four eggs.

and will practice flying from the nest. In early September they will launch on a solo journey along the Atlantic Flyway from Maine to South america via the Caribbean.

In the new study researchers used high-resolution micro-computed tomography (CT) scanners to analyze two fossils of leafcutter-bee nests excavated from the pits.

By examining the nest cell architecture and the physical features of the bee pupae (stage of development where the bee transforms into an adult from a larva within the leafy nests

and cross-referencing their data with environmental niche models that predict the geographic distribution of species the scientists determined their Ice age specimens belonged to Megachile gentilis a bee species that still exists today.

To reproduce females build small cylindrical nest cells made of carefully chosen leaves and sometimes flower petals.

The nests look like mini cigars Holden told Live Science. The bees build these multilayered nest cells in secure locations near the ground such as under the bark of dead trees in stems

or in self-dug burrows or those dug by other insects. In 1970 when scientists first excavated the two nest cells analyzed in the new study the cells together known as LACMRLP 388e were connected with an additional layer of leaves.

LACMRLP 388e was thought initially to be buds and only later after the two cells were separated accidentally did people suspect they might be bees.

and one female She decided to try to identify the bees'species. I had read some of the big literature that said leafcutter bees aren't really identifiable by their nest cells Holden said.

'Holden paired up with leafcutter-bee expert Terry Griswold an entomologist with the U s. Department of agriculture to try to pinpoint characteristics that distinguish between the nest cells of different leafcutter bee species. Piecing the evidence together The researchers

and examined micro-CT scans of the bee nest cells and discovered there are some differences in the way different leafcutter bees make their cells.

However the nest cells of LACMRLP 388e contained the cap as well as an uncommon circular base

They found essentially that M. gentilis was far more likely than M. onobrychidis to have lived in the La Brea area 23000 to 40000 years ago (the approximate age of the excavated nest cells.

The nest cells of LACMRLP 388e were constructed underground (but near the surface) in an area adjacent to the fossil-rich Pit 91.

Leaf matter used to construct the nest cells likely came from trees not far from the nest site suggesting the La Brea Tar pits had a nearby forest possibly containing streams or a river.

and grows faster forcing the other chicks out of the nest where they then die.

For several species of the<em>Stegodyphus</em>spiders motherly love goes even further than watching over the nest.

Eggs are laid in a communal nest called a dump nest which can hold about 60 eggs at one time.

Instead the primates build a new nest each evening from scratch. High up in the forest canopy the animals interlace strong stems

In 2011 one intrepid Cambridge researcher who slept in wild chimpanzee nests for six nights reported that the nests kept her warm and relatively free of bug bites;

Images of Primate Nests And now another group of researchers has looked at whether chimpanzees are picky about the type of wood they use for their nests.

Anthropologists David Samson of the University of Nevada Las vegas and Kevin Hunt of Indiana University in Bloomington examined 1844 chimpanzee nests in western Uganda's Toro-Semliki Wildlife Reserve.

They found that 73.6 percent of the nests were built with the plant species Cynometra alexandri

despite the fact that this tree was hardly the most common species in the area representing just 9. 6 percent of the local arboreal population.

Pairs will make nests out of mounds of mud and the female will lay one egg at a time according to the Smithsonian National Zoo.

but the census flights remain a primary tool for keeping tabs on the population. The annual bald eagle assessment involves two rounds of flights.

and involves systematically flying over all tributaries to check nests that we've recorded from previous years.

This part of the survey also includes mapping new nests constructed since the last breeding season.

Now that we know exactly where the eagles are nesting we fly back to each nest counting the number of new chicks.

For long stretches we see a nest every few seconds. Even with three experienced people doing the job we keep busy.

Eagles tend to nest in the same places often reusing a nest so out of the three of us we know

We remember those trees too. After flying over all those nests we've gotten pretty good at quickly gauging the age of eagle chicks by evaluating size and plumage.

These flights involve more than just keeping track of the numbers of breeding eagles in our territory.

Using data from nest counts and remote sensing imagery the research team found that the bonobo--one of humankind's closest living relatives--avoids areas of high human activity and forest fragmentation.

Specifically the team compiled data on bonobo nest locations collected by numerous organizations between the years 2003-2010.

This produced 2364 nest blocks with a block defined as a 1-hectare area occupied by at least one bonobo nest.

The results--which come from the largest ever study of wild bumblebee nests--could help farmers

otherwise destroy the eggs because of fierce competition for host nests. The new research is published today 21 august in the journal Biology Letters.

To obtain it they guide human honey-hunters to bees'nests. In return for showing the humans the bees the honeyguide gains access to the otherwise dangerous and impenetrable nest and its sought-after wax.

But these African birds also have a dark side. They are unusually vicious parasites whose imposter chicks stab the chicks of their host birds (often little bee-eaters) to death

The newly published research has shown that this fight for monopoly of the nest also extends to other honeyguides in a battle conducted deep underground in the nest burrows that bee-eaters dig into the roofs of Aardvark holes.

For example honeyguides parasitising little bee-eaters lay smaller eggs in their nests than do honeyguides parasitising larger hosts.

Many classic studies have shown that comparable mimicry in cuckoo eggs has evolved to reduce rejection by choosy hosts that eject mismatched eggs from their nests.

and experimentally parasitised their nests the bee-eaters blithely incubated eggs even much larger than their own.

and about a third of parasitised nests contain eggs laid by two or more honeyguide females resulting in especially strong parasitic competition.
