We have visited Decorah, Iowa and the nest a couple of times. 

      

  1. Where is this live cam located?

    This live cam overlooks a bald eagle nest just north of Decorah, Iowa. The nest sits in a white oak tree in a tiny forest bordering a secluded valley.  

How big is this nest?

Bald eagles are known for building massive nests over a period of years, and this is no exception! This nest is seven feet across at its widest point and nine feet long at its longest. It sits about 56 feet off the ground and the nest itself is 5.5 feet high. 

The first nest (DNN0) was built in a pine tree. The branches collapsed after the second nesting season and the eagles moved to a dead elm tree. They nested there for just one year before moving to their current location in late 2013. In August of 2018, their nest collapsed and slid or fell out of the nest tree during an extremely heavy storm. None of the tree branches were broken or damaged, so they decided to build a starter nest in the same spot. 2019 will mark their sixth season and second nest in this spot.  

How big are the Decorah Eagles?

Bald eagles measure 34-42 inches long and have wingspans between six and eight feet. They can weigh up to 14 pounds. 

How many young do the Decorah Eagles have at once?

Bald eagles typically have two eggs per year, but sometimes one or three. Both parents will incubate the eggs and after the eggs hatch, at least one parent will stay with the young at all times. 

Young bald eagles are entirely brown until they are about five years old, when they develop the distinctive white feathers on their head and tail. This is also the age when bald eagles begin to breed. 

Bald eagles tend to mate for life, and will return to the same nest year after year, as they have in this case.  

How long do bald eagles live?

Bald eagles have very long lifespans and can live upwards of 28 years in the wild. In one case, a bald eagle was banded in 1977 in New York state and was struck and killed by a car in 2015--38 years later.  

Do bald eagles migrate?

Some bald eagles migrate great distances while others are year-long residents of their habitats. The migratory patterns of bald eagles depend on age, weather, geography, and food availability. 

Where do bald eagles live?

The national symbol for the United States, bald eagles are found only in North America. Their range stretches from far northern Canada and Alaska down to northern Mexico.  

What do bald eagles eat?

A bald eagle's diet depends on its habitat, but typically bald eagles prefer to eat fish as well as birds and small mammals when fish are not available. Bald eagles are also known to eat carrion. These bald eagles eat live and dead fish from the nearby stream, as well as squirrels, birds, rabbit, deer, possum and other small animals.

Image result for balinese starling

This is a Balinese Starling. 

The Balinese Starling is also known as Jalak Bali, was originally found in the northwestern parts of Bali island, in an area called Curik. You can easily identify this unique species by its clear, white feathers, distinctive blue marks around its eyes, black wing tips and a striking plume of feathers atop its head. Both males and females have similar appearances, however the males are slightly bigger than the females.

saving-the-bali-starling-from-extinction

Other names for the Bali Starling are Bali Mynah or Rothchild’s Mynah. The latter name was given as a tribute to the British bird expert Walter Rothschild who first discovered the bird in 1911. To date, there are less than 100 Jalak Bali left in the wild. This is due to habitat loss and poaching. It’s fascinating to note that this bird can’t be found anywhere else in Indonesia although it was once said that some Jalak Bali were found in Lombok. Unfortunately, not a single bird can be found there now, so the fact remains that Jalak Bali is indigenous to the island of Bali.

Bohemian Waxwing

bohemian waxwing

 

Bohemian Waxwing is a medium-sized songbird with distinctive crested head and black masks. They are brownish-grey overall and wings have white and yellow edging. Thus, Bohemian Waxwing is among the most beautiful passerine birds in the world.

Bohemian waxwings inhabit in boreal forest across North America and Eurasia, mostly in Canada and Alaska. In winter, they migrate in large flocks to the Northwest parts of the United States. They nest on tree branches. Both male and female Bohemian Waxwings are known for their high pitched calls. They mainly feed on insects and berries.

 

I've never seen or even heard of this bird.  But it is so beautiful and full of color,  I thought he or she should be sited here for all to see.

We saw these birds on our trip to Costa Rica in August 2006. They are very friendly birds that would come to our table and beg for food when we at breakfast a the outdoor cafe.

FB_IMG_1557519402788.jpgFB_IMG_1557520522270.jpgFB_IMG_1557520538603.jpgFB_IMG_1557519458297.jpgFB_IMG_1557519450348.jpg

 

They also have a black throated magpie in Costa Rica. They are part of the Raven family. 

 

WHITE-THROATED MAGPIE JAY


Common Name: Magpie Jay

Type:
 Bird

Family: Corvidae

Range:
 The White-throated Magpie-Jay ranges from Mexico to Central America. These are available in the Mexico and most of the Central American countries like Costa Rica, Honduras, Guatemala, Nicaragua and El Salvador. They have a preference of the driest climates. The Guanacaste Province of Costa Rica has a large population of white-throated magpie-jays. They are also available in the National Parks of Costa Rica such as Carara National Park., Palo Verde National Park, Monteverde Cloud Forest Reserve and Rincón de La Vieja National Park.


Size:
 White-throated Magpie-Jay body length ranges from 46 to 56 centimeters. The Wingspan normally has a length from 178 mm to 193 mm. Tarsus length varies from 39 to 46 mm and bill length from 29 to 34 mm. Average length: 50.8 cm. Range wingspan:. Their average length is 50.8 centimeters and their wingspan ranges from 17.8 to 19.3 centimeters.

Weight: White-throated magpie-jays are big brilliantly colored bird’s body weight normally ranges from 205 g to 213 g.

Diet : White-throated magpie-jays are omnivores, they feed mostly on caterpillars and assorted small fruits. They also eat katydids and grasshoppers, frogs, small lizards, nestlings of small birds, and Acacia fruits and seeds. Other food includes assorted large fruits, arthropod egg and spiders. Their Diet differs from season, adult birds consuming generally fruit during (August-December) the dripping and late dripping season; caterpillars during the (May-August) early wet season, and a blend of miscellaneous fruit and acacia fruits during (January-April) the dry season.

Average life span: White-throated magpie-jays are likely to be relatively long-lived. While information on the lifespan of this particular species was not available, it is not uncommon for other species of corvids to live from 15 to 25 years.

Habitat: The White-throated magpie-jays habitat in a wide rage of environment. They mostly reside in drier habitats, mainly dry forests of the Costa Rica. They are also available in areas of semi-humid and woodland. They also make habitat near areas that are under cultivation. They are also available along the forest edges. They are frequently found near the places of human living and coffee plantations in the Central America. Preferred territories are usually flat, but they also found in hilly areas from sea level up to 1,250m ( 4,100 feet).

They usually make their habitat on thorny undergrowth and trees, mainly Acacia trees, which provide feeding in the dry season, and Cresenctia alata and Acrocomina vinifera trees that they utilize for nesting. Sometime they select an isolated tree in the middle of a clearing for nesting.

Breeding/Reproduction:
 White-throated magpie-jays are supportive breeders, family members provide help in breeding pair to raise young.

They generally breed from January to April. Each female lay 2 to 6 eggs. One female breeder is normally responsible for hatching all of the eggs of a small group of birds and seldom leaves the nest. Other females bring food to her during the incubation process. White-throated magpie-jays male do not play any active role in the reproduction process. The hatching period lasts about 23 days.
They generally breed once in the first 4 months of the year, however if the first nest is lost, the birds will lay more eggs. The age of the sexual maturity ranges between 8 to 14 months.


Magpie Jays
 are found in America in large quantities. They are quite different in appearance from the other members of their family. They are very loud and noisy birds and they usually travel in flocks.

The white throated Magpie Jays are mostly confused with the black throated magpie jays. They have a great resemblance.

They have the following three subspecies:-

1) Nominate race: It is found in southern Mexico.

2) C. f. Azure: They are mostly found in southeastern Mexico and western Guatemala.

3) C.f. Pompata: They are found in between eastern Mexico and Costa Rica.

C.f. Pompata have a height of 43-56 cm and they weigh about 205-213 kg. They usually have a long tail and have slightly curved shape soft bendable feathers on their head. These feathers have blue and black margins. Breast, belly and the underside of the rump are white. The mantle and the tail are blue with white margins on the tail. They have black colored eyes and legs. The beak is grey in color and the birds are of small size.

White-throated magpie Jay are not limited in terms of habitat. They can live in a diverse habitat. Similarly, they consume a lot of variety of animals and plants. They feed from the nectar in the flowers to the smallest insects. They will usually never have a shortage of food due to their ability to eat a lot of things.

Magpie Jay
 do not have the tradition of migration like other birds. They prefer to stay in the place where they are born. This is probably because the birds who have less food resources or who are not adjusting to the environment migrate to other places. But this is not the case with them as they can survive on a variety of foods and can adjust in different environments.

Magpie Jay are mostly referred to as compensating breeders. Every nest has a dominant female pair and several helpers to help in the growth of the offspring. They have a unique behavior that the female offspring remain in the nest to help their mother while male offspring are dispersed. The female offspring and helpers have the work of feeding the dominant female and its offspring. The dominant female mates only the dominant male. It is very faithful while all the other males are searching for a chance to mate with the dominant female. On the other hand the female workers want to be dominant in the group. Thus, everyone in the group wants a higher position. A new nest is only started when the first nest fails. Thus, another female gets the chance of being dominant.
These species are not listed as endangered. They can be found in great numbers in Costa Rica.

The young birds born need several years to be fully grown up. Their nests can be found in isolated trees in Costa Rica. They prefer to live alone.

History says that White throated Magpie jays rang as far south as the Nicoya Peninsula in Costa Rica.

They also also have a a black throat with a distinctive plume.

Image result for blue jay steller's jay

 

Blue Jay Adult

 

I know there are many, many different types of birds.  But the Blue Jay is my absolute favorite.  

 

Blue Jay Information

Blue jays are large for songbirds, typically measuring between 9 and 12 inches long, and weighing between 2.5 and 3.5 ounces. Distinguishing characteristics of the blue jay include the pronounced blue crest on their heads, which the blue jay may lower and raise depending on mood, and which will bristle outward when the bird is being aggressive or becomes frightened. Blue jays sport colorful blue plumage on their crest, wings, back, and tail. Their face is typically white, and they have an off-white underbelly. They have a black-collared neck, and the black extends down the sides of their heads - their bill, legs, and eyes are also all black. Their wings and tail have black, sky-blue, and white bars. Male and female blue jays are nearly identical.

Blue jays typically live in small flocks, and are highly protective of their nesting site. When flying alone, blue jays are subject to predation by hawks, eagles, and other raptors, however when in groups they will 'mob' much larger birds in order to fight them off. Blue Jays can imitate calls of their predators, especially hawks, and may use these calls to test whether or not these predators are in the area. They will also occasionally use these calls to scare other birds away from food sources that the blue jays have come across. In addition to raptors, blue jays may attack other animals, including humans, which come too close to their nests.

    

Blue Jay Facts

  • The coloration of the blue jay comes from light interference due to the internal structure of their feathers - if a feather is crushed, it will not maintain its blue coloration.
  • Blue jays are highly curious birds, and young blue jays have been known to play with bottle caps and aluminum foil.
  • Blue jays breed from mid-March to July.
  • Blue jays prefer to nest in evergreen trees and shrubs 10 to 35 feet off the ground.
  • Blue jays typically form monogamous pairs and stay together for life.
  • Blue jays normally fly at speeds of 20-25 miles per hour.
  • Blue jay eggs may be predated by squirrel, cats, crows, snakes, raccoons, possums, hawks, and various raptors and mammals.
  • There are four subspecies of blue jay: the northern blue jay, which live in Canada and the northern U.S. and has fairly dull plumage and pale blue coloration; the coastal blue jay, which lives on the southern coast of the eastern united states and is vivid blue; the interior blue jay, which lives throughout the midwest U.S.; and the Florida blue jay, the smallest subspecies, which is similar in color to the northern blue jay.

Courting Behavior: Male Feeding Female
Km
Source

During courtship, the male feeds seeds to the female. She will often flutter her wings and beg like a chick.

Male Cardinal feeding female
Male Cardinal feeding female | 

Nesting

After the courtship is over, the female builds a nest of twigs, vines, some leaves, bark strips, grasses, weed stalks, and rootlets, and lines it with fine grasses. She builds it in a thorny bush, thicket, or bramble, or in a dense shrub or tree. Up to six days later, she begins laying eggs, up to three or four total. They are somewhat glossy, grayish, bluish, or greenish-white, and spotted or blotched with brown, gray, or purple.

The female incubates the eggs for 11 to 13 days. A couple normally raises two to three broods each year.

Kauai has thousands of feral chickens. But how did they get there and why are they so well-adapted?

 
Photography
 

The Hawaiian islands, incredibly remote from any continent, were largely absent of large animals prior to Polynesian settlement in (this is disputed) somewhere between 300 and 800 AD. There were no mammals, besides some bats, and the largest animals were some mid-sized birds. Most everything in Hawaii, geologically speaking, is new, which is why imported animals can wreak so much havoc. A prime example would be the wild cattle of the Big Island, but on Kauai, a different kind of livestock has taken hold: the chicken.

Kauai is home to thousands of wild chickens, a particular variety that’s vibrant in plumage but of mixed value to the ecosystem of the island. They eat the venomous centipedes native to Kauai, a trait that people seem to like, but they have no natural predators besides pet cats and dogs, and the population is growing at an alarming rate. Some have even moved to other islands in the archipelago, like Oahu, where they’re not so welcome. But a team of researchers from Michigan State University is interested in the birds for an unexpected reason. Is it possible that the Hawaiian chicken could lead to hardier varieties of birds?

My folks had a cranberry bush which the Cedar Waxings loved to eat the berries. Here in Madison they were know to eat old berries, get drunk and fly into store windows on the Capital Square.  Photo is of a Saturday farmers market on the square. Cedar Waxwing is a medium-sized, sleek bird with a large head, short neck, and short, wide bill. Waxwings have a crest that often lies flat and droops over the back of the head. The wings are broad and pointed, like a starling’s. The tail is fairly short and square-tipped.

We have a young mother Cardinal nesting outside our living room window. You can see her red beak in the photos below. This is very interesting as we have had 3 or 4 pairs of Cardinals as long as we have lived here.  However, we have never found where they were nesting..
