Birds attracting

Bees (recognizing intense blue colors, insensitive to red), birds (attracted by vivid scarlets, sensitive to red), butterflies (attracted by bright colors), moths (attracted by dull and drab colors)... 

Reynolds Boids is a good example of decentralized order not because the boids behavior is a perfect replica of the flocking of birds that occurs in nature — although it is a close enough match that Reynold s model has attracted the attention of professional ornithologists — but that much of the boids collective behavior is entirely unanticipated, and cannot be easily derived from the rules defining what each individual bold does. 

In addition to their role in chemical defense, DMSP-lyase products may also function as chemical cue in more complex trophic cascades. In the natural environment DMS-production is related to zooplankton herbivory [60] and can thus act as an indicator for the availability of food for planktivorous birds. Indeed, some Antarctic Procellariiform seabirds can detect DMS (22) and are highly attracted to the cue, as was shown with DMS-scented oil slicks on the ocean surface [61]. The odors released during zooplankton grazing (DMS) as well as those of zooplankton itself (e.g., trimethylamine and pyrazines) are attractive to birds [62], thus assisting vertebrate search behavior. 

The landlocked Caspian Sea is the largest inland body of water on Earth. Surrounded by Azerbaijan, Iran, Kazakhstan, Russia, and Turkmenistan, the Caspian Sea is home to myriad ecosystems. At the meeting point of the Middle East, Europe, and Asia, the Caspian region includes steppe land in the north, cold, continental deserts and semi-deserts in the northeast and east, and warmer mountain and highland systems in the south and southwest. The coastal wetlands of the Caspian basin include many shallow, saline pools, which attract a variety of bird life and biodiversity over 400 species are unique to the Caspian. In addition, the sea s native sturgeon is famous the world around for the roe it produces sturgeon from the Caspian Sea accounts for approximately 90% of the world s caviar industry. 

Planting native species in the yard to replace turfgrass represents an effort to restore traditional and locally viable ecological communities on a small scale. Such species include not only historic and prehistoric forest species mixes (oak-hickory, and beech-maple for example), but also wddflower meadows, as well as tall and shortgrass prairie. The advantages of such landscapes are that they tend to be low-maintenance, resist weeds, and attract birds and other wildlife. Native landscaping also can be used to produce yards with fmit, nut and berry... 

Secondary compounds produced by plants may have other significant survival roles, such as signals to attract insects, birds, or other animals to enhance pollination or seed dispersal. In addition to any potential functions, secondary compounds may concomitantly serve a physiologic function, such as protection against ultraviolet (UV) light or frost, or provide a function in nitrogen transport and storage. In several instances, compounds can serve multiple functions in the same plant. Anthocyanins or monoterpenes can be... 

Attract insects that in turn are food for birds and bats ... 

Don t expect too much too soon you can only create the most suitable conditions for visits by wild birds, beasts, and insects, not drag them into your garden by force. Despite your best efforts, you may find that totally different species are drawn to your garden than those you originally intended to attract. 

The insects attracted by flowers, and especially their eggs, grubs, and caterpillars, will in turn become food for birds, predatory beetles, parasitic wasps, voles, and amphibians. Many creatures regarded as garden pests are actually a valuable food source for other creatures. 

A pond is not the only worthwhile water supply in a garden. Even the smallest water container will be attractive to birds and amphibians. Birds need water for daily bathing as well as drinking and will visit fresh clean water in any shallow type of container even an upturned trash can lid can be pressed into service. Sink the container into the ground, or build a ramp of bricks up to one edge to make it accessible to toads. 

Pick up fallen fruitlets, as these may house sawfly larvae. Earwigs may be found on fruits, but do not cause significant damage, and should be tolerated as they are excellent apple pest predators. In fall, remove mulches and rake up all fallen leaves, or mow over them so that they are taken down into the soil quickly, as they may harbor scab spores that could reinfect the tree in spring. Apply grease bands to trees and stakes to deter winter moths keep in place until early spring. After harvest, remove all unpicked fruits from the tree, and hang up fat to attract birds, which eat pests. 

Since virtually all communication by terrestrial vertebrates takes place in the air layer near the ground, the chemical ecologist has to understand the properties of that stratum. Volatiles in higher layers of air, however, may attract vultures to carcasses and could possibly serve as cues for migrating birds. Airborne odors are affected by temperature, relative humidity, barometric pressure, air currents, and vegetation, which, in turn, may influence temperature, humidity, and airflow. Complex interactions of these variables create countless unique environmental conditions for communication patterns of diverse species and for various specific purposes.
