Foreman’s Branch Bird Observatory

Spearheaded by long-term volunteer Bill Snyder, FBBO has banded 161 young Osprey since 1998. Ospreys build their nest on platforms placed on top of telephone poles, usually not far from water. 在初夏，我们监测鱼鹰平台的筑巢活动 并在6月和7月回来陪伴刚孵化的雏鸟.

Despite having banded a relatively small number of Osprey, we have had three recoveries. A nestling banded in July 2002 was found approximately 2,100 miles from FBBO in Trinidad in November later that same year. Our second recovery was of a nestling banded in 是2008年7月在厄瓜多尔发现的. Ecuador is approximately 2,700 miles away from FBBO. Lastly, a nestling banded in June 2018 was found dead 2018年11月，在距离FBBO 2091英里的哥伦比亚萨哈贡.

Osprey banding at the River and Field Campus provides a great way for volunteers to interact with these icons of the Chesapeake Bay region. The data collected from banding Osprey helps us determine how far they travel during migration and where they might winter. It also provides an opportunity to determine how many young Osprey hatch and eventually fledge from the nest platforms on the farm.

奇诺农场的不同地区有100多个蓝知更鸟箱. The original intent of these boxes was to monitor possible effects of agricultural by-products on cavity nesting birds. 虽然这方面的项目在几年前就结束了，但我们 still check the boxes during the breeding season.

Though the boxes were constructed primarily for Eastern Bluebirds, a variety of birds use them- Tree Swallows, Tufted Titmice, Carolina Chickadees, House Wrens, and Great Crested Flycatchers have all nested in the boxes. These boxes provide nest sites for cavity nesting birds which are often out-competed by aggressive non-native birds such as European Starlings and House Sparrows. The combination of box size specifications and frequent monitoring allows the native bird species to stave off the competitors.

The Eastern Bluebird Box trail provides an opportunity to study breeding phenology 比如筑巢、产卵、孵化和羽化的日期. In addition, maintaining nest boxes helps provide nesting habitat for Eastern Bluebirds, a once declining icon of open habitats throughout the East. To find out more information about Bluebird boxes visit the North American Bluebird Society. 要查看巢盒使用的详细摘要，请查看 FBBO Annual Reports below.

In the Fall of 2007 we learned a Northern Saw-whet Owl irruption was expected in the eastern United States. 一般来说，入侵是物种的周期性运动 due to food supplies or habitat availability. In years with great breeding success, there are too many Saw-whets to live off the resources available in the north and so large numbers of the owls migrate south in search of a place with adequate prey to spend the winter. A little research led us to Project Owlnet这是一个专注于锯磨猫头鹰的北美猫头鹰爱好者网络. From this group 我们学习了用于监控锯磨迁移的协议.

A small number of nets are run at night during late October and November and we play a standardized audio lure to attract owls. During Saw-whet Owl banding we have captured Eastern Screech Owls, and we have heard (but not yet caught) Barred Owls and Great Horned Owls in the woods. 猫头鹰的羽毛中含有一种叫卟啉的会发光的色素 in ultraviolet light. 这种色素会随着时间的推移而褪色，所以粉红色的亮度会减弱 可以用来老化羽毛和鸟，最粉红色的是最新的. The owl shown has a mix of young and old feathers.

Our Northern Saw-whet banding project contributes data to a continent-wide study of owl migration and distribution. These data can be pooled to help monitor population trends across North America.

You can track the number of Saw-whet Owls banded each fall by checking out the recent banding data.

Are birds dispersing ticks: we collect ticks from birds that have them and send them to researchers at Old Dominion University.  They are identifying them to see if ticks 它们是否通过搭乘候鸟来扩大活动范围.
