I think that the years he was most productive in were the twenties and thirties, but most people say his best years were from the fifties to the mid-sixties, from about "Strangers on a Train" to "Marnie".

"The Birds."
really? NO
Robins belong to the Aves class and are considered birds. Though normally very solitary, they do group. In the United States, they are called waves. In Great Britain, they are called rounds or breasts.
No they never fight. They race with the rival gang.
I think they are called whirlygigs. There are several sites on Whirly Gigs, Anders Lunde has a Book with plans and ideas on making them. Its called "Easy to make Whirly Gigs (woodworking Whirly Gigs) GOOD-LUCK ! Another excellent source is Meisel Hardware Specialties. They have many whirly gigs + other ornamental things to make. * www.meiselwoodhobby.com
The installation of Whirly Birds involves several key steps to ensure they function effectively and enhance ventilation in homes or buildings. Here's a breakdown of the process: Key Steps in Installing Whirly Birds: Site Assessment: A thorough inspection of the roof is done to determine the ideal placement for optimal airflow. Typically, Whirly Birds are installed in locations where heat and moisture accumulate, such as attics or upper areas of buildings. Selecting the Right Size and Quantity: The size and number of Whirly Birds required depend on the size of the building and its ventilation needs. Larger buildings may require multiple units to ensure adequate airflow. Marking Installation Points: After determining the best spots, the installer marks the roof area where the Whirly Birds will be mounted. It's crucial that the placement avoids obstacles like rafters and beams. Cutting the Roof Opening: A hole is cut through the roofing material at the marked spots. The size of the hole matches the base of the Whirly Bird to ensure a snug fit. Installing the Flashing: Roof flashing is installed around the base of the Whirly Bird to ensure it is watertight and prevent leaks. This step is essential for weatherproofing and the longevity of the installation. Attaching the Whirly Bird Unit: The Whirly Bird is securely fastened to the roof over the hole, ensuring it is tightly affixed and aligned correctly. Some models include adjustable bases to fit different roof pitches. Sealing and Testing: Finally, the installer seals around the base and flashing to protect from moisture. Once installed, the Whirly Bird is tested to ensure it spins freely, allowing for maximum airflow. How Whirly Birds Improve Ventilation Efficiency: Whirly Birds work through a wind-driven mechanism. As wind blows, the turbine spins, pulling hot, moist, and stagnant air out of the attic or upper levels of the building. This process has several benefits: Temperature Regulation: By removing hot air, Whirly Birds help lower the internal temperature, especially in attics. This reduces the need for air conditioning and improves energy efficiency. Moisture Reduction: Proper ventilation reduces the buildup of humidity, preventing mold growth, wood rot, and other moisture-related damage. Increased Air Circulation: By continuously extracting warm air, Whirly Birds improve the overall airflow within the building, contributing to a healthier indoor environment. For professional Whirly Birds installation and roof ventilation solutions, The Sydney Roof Doctor offers expert services to enhance the comfort and efficiency of your home or business.
Whirly Birds improve ventilation by using wind power to extract hot air and moisture from inside a building. As the wind moves over the turbine, it spins, creating a vacuum effect that pulls out stale air from the roof space. This continuous airflow helps to reduce heat buildup in summer and prevents condensation in winter, which can lead to mold and structural damage. Proper ventilation through Whirly Birds can also lower energy costs by reducing the need for air conditioning. They operate without electricity, making them a cost-effective and environmentally friendly solution for improving indoor air quality.
