Birds need to alter their metabolism in order to meet the demands of migration. The storage of energy through the accumulation of fat and the control of sleep in nocturnal migrants require special physiological adaptations. In addition, the feathers of a bird suffer from wear-and-tear and require to be molted. The timing of this molt - usually once a year but sometimes twice - varies with some species molting prior to moving to their winter grounds and others molting prior to returning to their breeding grounds. Apart from physiological adaptations, migration sometimes requires behavioural changes such as flying in flocks to reduce the energy used in migration or the risk of predation.
How do birds store energy?
A: through the accumulation of fat and the control of sleep

The Crimean War was one of the first conflicts to use modern technologies such as explosive naval shells, railways, and telegraphs.(Preface) The war was one of the first to be documented extensively in written reports and photographs. As the legend of the "Charge of the Light Brigade" demonstrates, the war quickly became an iconic symbol of logistical, medical and tactical failures and mismanagement. The reaction in the UK was a demand for professionalization, most famously achieved by Florence Nightingale, who gained worldwide attention for pioneering modern nursing while treating the wounded.
Who was recognized for treating the wounded while pioneering modern nursing?
A: Florence Nightingale

It was not unusual for electric recordings to be played back on acoustic phonographs. The Victor Orthophonic phonograph was a prime example where such playback was expected. In the Orthophonic, which benefited from telephone research, the mechanical pickup head was redesigned with lower resonance than the traditional mica type. Also, a folded horn with an exponential taper was constructed inside the cabinet to provide better impedance matching to the air. As a result, playback of an Orthophonic record sounded like it was coming from a radio.
What adjustments were made to the orthophonic to accommodate electric recordings?
A: mechanical pickup head was redesigned with lower resonance than the traditional mica type

Southeast Tucson continues to experience rapid residential development. The area includes Davis-Monthan Air Force Base. The area is considered to be south of Golf Links Road. It is the home of Santa Rita High School, Chuck Ford Park (Lakeside Park), Lakeside Lake, Lincoln Park (upper and lower), The Lakecrest Neighborhoods, and Pima Community College East Campus. The Atterbury Wash with its access to excellent bird watching is also located in the Southeast Tucson area. The suburban community of Rita Ranch houses many of the military families from Davis-Monthan, and is near the southeastern-most expansion of the current city limits. Close by Rita Ranch and also within the city limits lies Civano, a planned development meant to showcase ecologically sound building practices and lifestyles.
What community college is in southeast Tucson?
