I'm out of here - running away. Watching the juvi burrowing owl run is a sight to be seen. Will certainly make you smile!
Day one hundred seventy-eight/365. They're predicting another winter storm, to begin tomorrow and to last into Wednesday.
It's interesting to see the variety of ways people react to such forecasts. It's especially curious to observe the people who take precautions to an extreme.
Of course, grocery stores become crowded with people stocking up on milk and bread, as if they're expecting to be isolated in their homes for a week. Not older people, who may remember those experiences, but younger folks.
In addition, professionals who work by appointments tell me that numbers of people cancel as soon as the forecast is published.
I know a woman who owns a large 4wd pickup, but will not leave her garage if there are flurries in the air.
Are people using the opportunity to stay home and relax? There might be some merit to that decision! If not, and if they're taking caution to an extreme, then I wonder what other ways they apply that sense of caution...
Behavior Study 3: this young Herring Gull repeated dropped and retrieved a stick in the water. Was it "play", skill training, or a mix of both?
A text, in english, from Wikipedia, the free encyclopedia:
The Burrowing Owl (Speotyto cunicularia) (ex-Athene cunicularia) is a small, long-legged owl found throughout open landscapes of North and South America. Burrowing owls can be found in grasslands, rangelands, agricultural areas, deserts, or any other dry, open area with low vegetation (Lewis 2005). They nest and roost in burrows, such as those abandoned by prairie dogs. Unlike most owls, burrowing owls are often active during the day. However, most hunting is done at dusk or at night.
Burrowing owls are able to live for at least 9 years in the wild and over 10 years in captivity.[citation needed] They are often killed by vehicles when crossing roads, and have many natural enemies, including badgers, coyotes, and snakes. They are also killed by both feral and domestic cats and dogs.
Burrowing owls have bright yellow eyes. The bill can be yellow or greenish depending on the subspecies. The legs are incompletely feathered, and the toes are grayish in color. They lack ear tufts and have a flattened facial disc. The owls have prominent white eyebrows and a white "chin" patch which they expand and display during certain behaviors.
Adult owls have brown upperparts with white spotting. The breast and belly are white with variable brown spotting or barring. Juvenile owls are similar in appearance, but they lack most of the white spotting above and brown barring below. Also, the young owls have a buff bar across the upper wing and their breast may be buffy rather than white.
Males and females are similar in size and appearance. However, adult males sometimes appear lighter in color because they spend more time outside the burrow during daylight, and their feathers become sun-bleached. The average adult is slightly larger than an American Robin, at 25 cm (10 inches) length, 53 cm (21 inches) wingspan, and 170g (6 oz) weight (Lewis 2005).
The typical "who who" call of a burrowing owl is associated with territory defense and breeding, often given by adult males to attract a female to a promising burrow. They also make other sounds, which are described as chucks, chattering, and screams. These sounds are usually accompanied by an up and down bobbing of the head. When alarmed, young birds will give a hissing call - a case of acoustic Batesian mimicry - that sounds like a rattlesnake (Haug et al. 1993).
Before European colonization, burrowing owls probably inhabited every suitable area of the New World, but they have experienced some restrictions in distribution since. They range from the southern portions of the western Canadian provinces through southern Mexico and western Central America. They are also found in Florida and many Caribbean islands. In South America, they are patchy in the northwest and through the Andes, but widely distributed from southern Brazil to Patagonia and Tierra del Fuego.
Burrowing owls are year-round residents in most of their range. Birds that breed in Canada and northern USA usually migrate south to Mexico and southern USA during winter months.
The burrowing owl is endangered in Canada[1], threatened in Mexico, and a species of special concern in Florida and most of the western USA. It is common and widespread in open regions of many Neotropical countries, where they sometimes even inhabit fields and parks in cities. In regions bordering the Amazon Rainforest they are spreading with deforestation. It is therefore listed as Least Concern on the IUCN Red List.
The major reasons for declining populations in North America are control programs for prairie dogs and loss of habitat, although burrowing owls readily inhabit some anthropogenic landscapes, such as airport grasslands or golf courses (Korfanta et al. 2005).
Burrowing owls are protected under the Migratory Bird Treaty Act in Canada, the United States, and Mexico. They are also included in CITES Appendix II.
Genetic analysis of the two North American subspecies indicates that inbreeding is not a problem within those populations (Korfanta et al. 2005).
The nesting season begins in late March or April in North America. Burrowing owls are usually monogamous, but occasionally a male will have two mates (Lewis 2005). Pairs of owls will sometimes nest in loose colonies. Their typical breeding habitat is open grassland or prairie, but they can occasionally adapt to other open areas like airports, golf courses, and agricultural fields. Burrowing owls are slightly tolerant of human presence, often nesting near roads, farms, homes, and regularly maintained irrigation canals.
The owls nest in an underground burrow, hence the name Burrowing Owl. They use burrows created by other burrowing animals such as prairie dogs, ground squirrels, or badgers (Holt et al. 1999). If burrows are unavailable and the soil is not hard or rocky, the owls may excavate their own. Burrowing owls will also nest in shallow, underground, man-made structures that have easy access to the surface.
The female will lay as many as 8-12 eggs over a two week period. She will then incubate the eggs for three to four weeks while the male brings her food. After the eggs hatch both parents will feed the chicks. Four weeks after hatching, the chicks are able to make short flights and begin leaving the nest burrow. The parents will still help feed the chicks for 1 to 3 months. While most of the eggs will hatch, only four to five chicks usually survive to leave the nest.
During the nesting season, burrowing owls will line the burrow with mammal dung, usually from cattle. The dung helps to control the microclimate inside the burrow and to attract insects, which the owls may eat (Levey et al. 2004).
Site fidelity rates appear to vary among populations. In some locations, owls will frequently reuse a nest several years in a row. Owls in migratory northern populations are less likely to return to the same burrow every year. Also, as with many other birds, the female owls are more likely to disperse to a different site than are male owls (Lutz & Plumpton 1999).
The highly variable diet includes small mammals, small birds, snakes, lizards, frogs, insects, and scorpions. But the owls mainly eat large insects and small rodents. Although burrowing owls often live in close proximity to ground squirrels, they rarely prey upon them. Unlike other owls, they also eat fruits and seeds, especially the fruit of tasajillo (Cylindropuntia leptocaulis) and other prickly pear and cholla cacti. When hunting they wait on a perch until they spot prey. Then they swoop down on prey or fly up to catch insects in flight. Sometimes they chase prey on foot across the ground.
The burrowing owl is sometimes separated in the monotypic genus Speotyto. This is based on an overall different morphology and karyotype. On the other hand, osteology and DNA sequence data suggests that the Burrowing Owl is just a terrestrial version of the Athene little owls, and it is today placed in that genus by most authorities.
A considerable number of subspecies have been described, but they differ little in appearance and the taxonomy of several needs to be validated (Holt et al. 1999). Most subspecies are found in the Andes and the Antilles. Only A. c. hypugaea and A. c. floridana are found in North America. Although distinct from each other, the relationship of the Floridan subspecies to (and its distinctness from) the Caribbean birds is not quite clear (Korfanta et al. 2005).

Reino: Animal
Filo: Vertebrado
Classe: Aves
Ordem: Strigiformes
FamÃlia: Strigidae
Ave muito interessante e com caracterÃsticas peculiares é tida pelo povo grego como a ave da sabedoria. Outros povos porém, acham que causa azar e arrepios seu canto quando rasga o silêncio noturno. Dizem ainda que é sinal de mal agouro e que o seu canto está pressagiando alguma tragédia, o que é pura crendice popular, pois o que se sabe é que as corujas são muito úteis ao homem predando pragas nas lavouras e controlando a população de ratos ao redor das cidades e no campo.
Pode girar seu pecoço em 270º
CaracterÃsticas:
A coruja-buraqueira é muito comum pelos campos do Brasil.
Mede em torno de 20-30 cm com envergadura de 50-61cm e pesando em média 170g.
Com peito branco e plumagem amarelada o macho é ligeiramente maior que a fêmea, possuem cabeça arredondada e são aves muito tÃmidas.
Com olhos grandes e amarelos, a coruja-buraqueira tem a visão 100 vezes mais aguçada que a do homem e seus olhos estão dispostos frontalmente, como os do ser humano.
Quando necessita olhar algum objeto ao seu redor gira o pescoço em um ângulo de até 270 graus, aumentando assim o seu campo visual.
Essa disposição frontal, proporciona à coruja uma visão binocular (enxerga um objeto com ambos os olhos e ao mesmo tempo), isso significa que a coruja pode ver objetos em três dimensões, ou seja, altura, largura e profundidade.
Pode julgar distâncias similares ao ser humano e seu campo visual é de 110 graus, sendo 70 graus de visão binocular.
Os olhos da coruja-buraqueira são bem grandes, em algumas espécies de corujas até maiores que o próprio cérebro, a fim de melhorar sua eficiência em condições de baixa luminosidade, captando e processando melhor a luz disponÃvel.
Além de sua privilegiada visão, a coruja-buraqueira é dona de uma audição potentÃssima, conseguindo localizar e abater sua presa com apenas este sentido.
Abate preferencialmente pequenos roedores, insetos, anfÃbios e pássaros. A coruja é uma ave de rapina, portanto mata para se alimentar. A tradução da palavra rapina é "roubo", o que caracteriza o fato de tais aves retirarem a vida de suas presas.
Rapineira e atenta à tudo
A coruja como a grande maioria dos animais possue território de caça. São ""equipadas "" com adaptações especiais que as tornam predadoras eficientes, sendo uma delas o vôo.
Sempre muito silenciosa e sorrateira, isso devido à s penas especiais de sua asa, muito macias e em grande quantidade, conseguem cortar o ar e planar por muito tempo sendo muito discretas e imperceptÃveis à s suas presas.
A observação das presas se dá no alto de árvores ou em mourões de cercas nos pastos e até durante o vôo silencioso, quando fazem uma varredura na área de caça. Quando um alvo é avistado a coruja voa silenciosamente até ele, mantendo sua cabeça em linha reta ao alvo, quando então a joga para trás e empurra suas garras para frente a fim de prender seguramente sua presa. A força do impacto é violenta e certeira não dando chances à presa. Posteriormente a vÃtima é morta pela pressão do bico, num processo de abatimento de presas no solo.
O perÃodo reprodutivo da coruja-buraqueira começa nos meses de março e abril, os ninhos são feitos no solo, aproveitando antigas tocas de tatus ou simplesmente promovem a abertura de novos ninhos, num trabalho revezado entre o casal.
Os ninhos são escavados com os pés e bicos, formando uma galeria horizontal de até 3 m de profundidade por 30cm-60cm de largura.
Em média botam de 6 a 12 ovos, que são incubados por 28 dias pela fêmea; fica por conta do macho proteger o ninho e procurar alimento para toda a prole.
Com 14 dias os filhotes já ficam empoleirados na saÃda da cova, aos 44 dias saem do ninho e com 60 dias estão caçando pequenos insetos.

This originally opened as Burton Funeral Home in 1987. In 1999, Burton Funeral Home closed down and was vacant for two years. In 2001, Evans Capital Management opened. In 2014, Evans closed and was replaced with Northwest Bank. In 2019, Northwest Bank closed and was replaced with LECOM Behavioral Health in 2020.
This is a defensive behavior of a male Mute Swan (Cygnus olor) as it chases Greylag geese away from ithe swan's newly hatched offspring. The young cygnets are foraging for food along the shoreline (just out of frame) with their mother (known as a pen).
The male Mute Swan (known as a cob) is aggressive in defense of its nest and its young. His size and impressive hissing make it a formidable adversary for animals as large as a fox. Large waterfowl, such as geese, are easily driven off.
This dramatic moment takes place at the fantastic waterways and gardens at the Flowered Island of Seven Hills (Blumeninsel Siebenbergen) located at the Staatspark Karlsaue on a spring day in Kassel, Germany.
After successfully swimming through the hoop, a food pellet is delivered and a red light comes on (to signal that they earned the food).
We took a Cessna 206 to Katmai National Park. It was an incredible experience being within 30 feet of bears in the wild and observing their behavior. It was interesting to see how each bear reacted to the presence of humans.

Our program targets at risk teens through mind, spirit, and body intervention with activities aimed at behavior modification. Mount Carmel Youth Ranch (MTC) was founded in 1992 and is located on a 40,000 acre working cattle ranch in northwest Wyoming. Mt. Carmel is a non-profit organization dedicated to helping young men with behavioral issues.
Yesterday morning I found this unusual scene (for me), two Jumpers in a strange behavior. I think it's a mating behavior, but I'm confused.
Here a 2x magnification!
smoking baby part 2, and like a few hours after i took this picture we were walking around manhatten and stumbled upon a thrift store which just so happens to sell a toy called the smoking baby...i never even knew it existed
Jimmy Dean has had this tennis ball for years - I pulled the skin off of it. Every once in a while Jimmy Dean will lick this ball, slowly moving it around for 10 or 15 minutes.
Pictures of the Winter in July event at the Phoenix Zoo. This annual event includes snow trucked in for the event, a chilly 'blizzard' every 30 minutes, and snow themed events with the animals. There were four different animal events that featured behavioral enrichment, a process of ensuring captive animals in zoos are treated for psychological and physiological well-being. I will list all the events separately. I learned on their site that they were looking for volunteers. So I was on their website to learn about the event when I learned that they needed volunteers! So I signed up as a photographer and snow shoveler. I was part of a crew of volunteers who broke up the snow so the kids could play with it. It has a hard ice crust the moment we arrived and had to continually work the snow to make it fun to play with. Very glad to spend the day at the Zoo helping them pull off this event. Here are pictures of the very popular elephant shower that is one of the highlights of this annual event (from what I understand). Reba is an Asian Elephant who is around 45 years old. She is sprayed with the fire hose. When they were done, they showered the audience and my camera bag got soaked! Oh well - all is fine. Thanks to the Phoenix Fire Department for supplying the firehose!
Held Thursday 09/14/2017, the Center on Finance, Law, and Policy hosted a symposium discussing behavioral finance. This event included keynote speakers, interdisciplinary panel discussions, and an interactive audience experiment, exploring topics of technological progress in our overall economy.

CALIFORNIA SEA OTTERS
Animal Classification
Sea Otter (Enhydra lutris)
Description
Sea otters are members of the weasel or mustelid family. Like other members of this family, they have very thick fur. In fact, at 850,000 to one million hairs per square inch, they have the thickest fur of any mammal. Their fur actually consists of two layers, an undercoat and longer guard hairs. This system traps a layer of air next to their skin so their skin does not get wet. Sea otters are usually dark brown, often with lighter guard hairs. Alaskan sea otters tend to have lighter fur on their heads. Sea otters are the smallest marine mammals. In California adult females weigh 35-60 pounds (16-27 kg); males reach up to 90 pounds (40 kg). Alaskan sea otters are bigger with males weighing up to 100 pounds (45 kg).
Range/Habitat
Sea otters once ranged from Mexico to Alaska and even to Japan. Currently, the California population numbers around 2,800 and is found from Half Moon Bay to Morro Bay. There is a much larger population in Alaska, and sea otters are still found in Russia. Sea otters inhabit shallow coastal areas and prefer places with kelp. The kelp acts as an anchor that the sea otters use to wrap themselves in when they are resting.
Mating/Breeding
Females give birth to one pup and usually have their first pup at the age of four or five. Their pregnancies last four to five months. Pups can be born any time of year, but in California most are born between January and March, and in Alaska most are born in the summer. When born, the pups weigh from three to five pounds.
Behavior
Sea otters are social animals, with females and pups spending time together in one group and males in another. Pups stay with their mothers for the first eight months of their life. The pups' fur traps so much air that they actually cannot dive under water. When mothers leave the pups wrapped in kelp to hunt, pups bob on the surface of the ocean like a cork. Mothers spend much time grooming pups and often carry them on their chests. Pups begin to learn to swim at around four weeks of age. Sea otters are one of the few animals to use tools. They eat animals with shells, like clams and abalone, and use a stone to break open the shells. When sea otters are under water searching for food, they store what they have found in the loose skin folds at their armpits. Adult sea otters can eat 25%-30% of their body weight in one day!
Status
Sea otters in California are a threatened species due to past over hunting for their beautiful fur. Although sea otters are protected now, they remain vulnerable, especially to oil spills. Unlike other marine mammals, sea otters do not have a blubber layer. Therefore, they rely on their fur to keep warm. If their fur is oiled, it loses its insulating qualities and the sea otters soon chill. Otters are also affected by the oil fumes or poisoned by eating food exposed to oil. Most sea otters quickly die in an oil spill. Several thousand sea otters died in the 1989 Exxon oil spill in Valdez, Alaska. Other threats to sea otters include infectious diseases, parasites, boat strikes, entanglements, and toxins.
At The Marine Mammal Center
The Marine Mammal Center began rehabilitating sea otters in 1995. Since that time, we have rescued up to 207 sea otters.
