Banding



Nature Area) containing remnant riparian cottonwood forest habitats along the Missouri River in central South Dakota during spring and fall migrations. These habitats have continued to decline in the more than 50 years since Lake Sharpe was created. GFP has banded each spring and fall at Farm Island Recreation Area since 1992. In the spring of 2004 we opened a second banding station at Fisherman Point, located within the Oahe Downstream Recreation Area. The year 2011 was the exception to the consecutive string of spring and fall banding sessions when extreme flooding prevented access to the sites.

We band at a private home and space is limited. To visit hummingbird banding you must sign up ahead of time. Registration typically opens in early spring.


Our National Bird Banding Office coordinates the New Zealand National Bird Banding Scheme (NZNBBS). It leads the certification process and issues banding certificates. It also supports the training of banders, manages banding data and supplies bands and other equipment to banders.


Bio-banding allows players to be grouped based on their maturity and biological age and not by their chronological age. By doing this, massive swings in maturity that can be seen within the current chronological groupings are removed. By grouping players based on maturity, the physical advantages that early maturing players have when playing against less mature players are reduced.


As an additional player development tool, bio-banding will allow participating Academy club coaches and staff, and U.S. Soccer Talent Identification to evaluate players in an environment where physical advantages are less of a factor. After the event, the U.S. Soccer High Performance department will continue to work with all Development Academy clubs looking to expand their player development tools with Bio-Banding.


Bird banding is one of the oldest and most important techniques used for studying and identifying individual birds. In the early 1800s, John James Audubon tied threads to birds' legs to identify individuals that were visiting his farm. In 1902, the first scientific study to use bird banding took place in the United States: Smithsonian scientists attached bands to the legs of black-crowned night herons at the Smithsonian's National Zoo in Washington, D.C.


In many countries, bird banding is regulated by the federal government. In the U.S., the Bird Banding Laboratory (BBL), part of the United States Geological Survey, provides scientists with aluminum bands and keeps records on all banded birds. Scientists must submit an application to receive bands from the BBL. They are required to show proof of their skill in safely handling birds, explain why they need to band birds as part of their research and provide information on where the research will take place. Each bird that is given a tracking device, such as a light-level geolocator or satellite transmitter must also be banded.


In most studies, researchers encounter less than one in five banded birds between seasons. These chances get increasingly smaller the farther birds travel from the location where they were banded. Because the chances of encountering a banded bird again can be low, banding data is of limited use when it comes to tracking migratory birds throughout their annual cycle. Despite these limitations, banding can be a very useful tool for studying non-migratory birds or birds in their wintering or breeding territory.


When a color-banded bird is re-sighted, scientists can use the time and location that the bird was seen to gain valuable information. Identifying the bird one or more times gives an indication of how long it survives. Observations of the color-banded bird at locations outside of the banding site can indicate the distance that the bird moves during or between seasons.


A challenge to color banding is that it takes considerable time and effort to search for and identify the banded birds. The likelihood of re-sighting color-banded birds decreases the farther the bird travels from where it was banded. Because of this, color banding birds is not a great technique to track where birds move throughout their annual cycle. This makes color banding birds a great tool for answering questions about birds that will stay in a certain area throughout a study, but it is of very limited value when researching birds that travel greater distances.


Reservations required for groups. To schedule group visits, contact Chico Basin Ranch by email or phone: (719) 683-7960. The ranch and banding station are now open to the public (ranch access fee of $15, payable at ranch HQ).


Adjustable gastric banding should not be used for someone who is a poor candidate for surgery, has certain stomach or intestinal disorders, has to take aspirin frequently, or is addicted to alcohol or drugs. It should not be used if someone is not able or willing to follow dietary and other recommendations, or for whom frequent visits to the office are prohibitive.


Options for surgical management of morbid obesity include restrictive (adjustable gastric banding, vertical band gastroplasty), restrictive/resective (sleeve gastrectomy), restrictive/malabsorptive (Roux-en-Y gastric bypass, biliopancreatic diversion with duodenal switch) and purely malabsorptive (duodenal switch) options. Of the various available options, restrictive surgical techniques have been a mainstay of treatment for morbid obesity for several decades. In this light, adjustable gastric banding represents one of the more frequently performed bariatric operations in morbidly obese patients.7 Laparoscopic adjustable gastric banding (LAGB) is considered to be a safe and effective method of weight loss and reduction of comorbidities associated with obesity.8 Despite its improved early safety profile compared with Roux-en-Y gastric bypass, patients with LAGB can manifest unique complications that are distinctive to the LAGB and require a specific process for assessment and management.


Since wood ducks live in densely vegetated habitats, it is difficult to monitor their populations through typical aerial waterfowl surveys. Instead, LDWF primarily uses banding to assess wood duck populations. Biologists attach a uniquely numbered band around the leg of a captured wood duck, record information about the duck, and release it. This information is stored in a centralized database at the Bird Banding Laboratory of the U.S. Geological Survey. Biologists use information from bands subsequently found and reported back to the Lab to assess wood duck movements between regions where they are banded and where they are recovered; estimate annual survival rates; and evaluate harvest rates.


Figure 1 shows the locations of wood ducks banded in Louisiana and recovered during the hunting season immediately following the pre-season banding period each year. These are called direct recoveries. We use direct recoveries to estimate the harvest rate or the proportion of the population harvested by hunters.


Figure 2 shows indirect recoveries, or the locations of wood ducks banded in Louisiana that are recovered more than a year after the pre-season banding period. Indirect recoveries from many years of banding and recovery are necessary to estimate survival rates of Louisiana wood ducks.


Control banding is an assessment method that can be used to manage workplace risks. It is a process that matches, for example, a control measure (e.g., ventilation, engineering controls, containment, etc.) to a range or "band" of hazards (e.g., skin/eye irritation, very toxic, carcinogenic, etc.). The control banding method also groups chemicals according to similar physical or chemical characteristics, how the chemical will be handled or processed, and what the anticipated exposure is expected to be. The method then determines a set of controls chosen to help prevent harm to workers.


Control banding was originally developed by the pharmaceutical industry as a way to safely work with new chemicals that had little or no toxicity information. These new chemicals were classified into "bands" based on other more-studied materials' toxicity and anticipated safe work practices, taking into consideration exposure assessments. Each band was then aligned with a control scheme. For this reason, control banding is commonly associated with chemical exposures but similar systems are available for other workplace hazards.


The overall goal of control banding is to help workplaces by providing an "easy to understand" and "easy to apply" approach to controlling hazards. The control banding method is generally meant to be used by small- and medium- sized workplaces that have limited expertise in workplace health and safety, industrial hygiene, or chemical control.


Control banding is based on the idea that while there are many chemicals that workers can be exposed to, in practical terms, there are only a limited number of common approaches to hazard control to protect workers. These approaches are grouped into levels based on how much protection the approach offers (with "stringent" controls being the most protective). The greater the potential for harm, the greater the steps needed for control.


Control banding offers a way to assess risks and choose relevant control measures to reduce exposures in workplaces. It also allows for control recommendations to be made for products that do not have occupational exposure limits.


Control banding as a method is not fully validated yet - there is need for continued testing of control recommendations and the actual exposure to workers. There is no universally adopted (i.e. no single "correct") method of control banding, and each method has limitations. As such, employers should still monitor and evaluate any control measures used in the workplace.


Recommendations developed by a control banding method may need to be reviewed by a health and safety professional to make sure that the control strategy is appropriate, adequately designed, properly installed, and maintained to keep worker exposure within acceptable limits. Monitoring is also required to check that the control methods are working properly. 350c69d7ab
