Some birds, like crows, prefer to build their nest high in the tree tops. Baltimore orioles attach their basket-like nest about 25–30 feet high in a tree. An American robin will nest anywhere from 3–25 feet high and the red-winged blackbird weaves its nest into grasses near wetland areas about 3 feet from the ground. There are also ground Bird Nests nesters such as the eastern meadowlark.

  • 17 Year Periodical Cicada - Magicicada Cassini and Magicicada Septendecim
    Problem: 17 Year Periodical Cicada - Magicicada cassini and Magicicada septendecim Hosts: Over 270 species of plants serve as hosts though the most preferred plants include maple, hickory, hawthorn, apple, peach, cherry, and pear. Pine and spruce trees are not damaged. Description: Periodical cicadas show up every 17 years in Kansas with 2015 being the last year of emergence. The year of emergence varies with location. For example, a brood of periodical cicadas emerged in 2013 in Maryland, Virginia, and portions of Pennsylvania, West Virginia and North Carolina. Since our last year of emergence was 2015, our next will be 2032. However, there are always some cicadas that emerge 4 years early. Therefore, we will see a partial emergence in 2028. The bodies of periodical cicadas are basically black but the basal portions of the wing veins are distinctly orange and the eyes are reddish/orangish. No other species of cicada in Kansas fits this description. Cicadas do not sting or bite. Life History: In May and June of the year of emergence, matured nymphs will emerge from the ground and climb onto trees, bushes and other upright structures. After securing a good foothold, a split will form at the head end of each nymph, and the adult will emerge. Female cicadas will use their ovipositors to insert eggs beneath the bark of twigs and branches on a wide variety of trees and shrubs. Eggs will hatch in seven to eight weeks, and the nymphs will drop to the ground, burrowing as deep as 24 inches into the ground until they find suitable roots upon which to feed.

  • Periodical Cicada, 17-Year Locusts
    Pest Profile Photo credit: Jim Kalisch, University of Nebraska - Lincoln Common Name: Periodical cicada, 17-year locusts Scientific Name: Magicicada septendecim (Linnaeus) Order and Family: Hemiptera, Cicadidae Size and Appearance: This species of cicada goes through a 17-year life cycle. The nymphs live underground, feeding and growing for 17 years, then emerge in large numbers to breed and start the cycle again. When the nymphs emerge, they find a tree to climb and shed their skin. The different broods that occur every 17 years are given specific Roman numeral designations. Males sing using a special organ to produce a loud noise that attracts the females to mate. Length (mm) Appearance Egg Eggs rice like in appearance. The eggs are laid in branches of trees in slits, where they hatch and drop to the ground. They burrow into the ground, where they remain for the rest of their nymphal life. Larva/Nymph Tan or brownish in color, no wings, front legs modified for burrowing and clinging on tree. Nymphs undergo five instar stages, growing slowly for 17 years. Most of the life cycle is spent underground until it emerges and molts to an adult to mate. Adult 27-30mm, Adults have black bodies, red eyes, and membranous reddish wingspan 76mm orange wings. Can crawl and fly; short antennae; 3 ocelli; males sing loud choruses, females don’t sing. Pupa (if applicable) Type of feeder (Chewing, sucking, etc.): Nymphs and Adults: Piercing-sucking Host plant/s: They feed on a wide variety of deciduous trees and roots of trees. Description of Damage (larvae and adults): As nymphs, the periodical cicadas suck juices and nutrients from roots of trees.

  • Cicadas - Getting Ready for Brood X
    Best Management Practices Cicadas - Getting Ready for Brood X This year marks the emergence of Brood X throughout the Mid-Atlantic States. Experts are predicting this year’s emergence to be the most numerous in history. These Periodical cicadas (belonging to the genus Magicicada) are considered nuisance pests and do not bite, sting, and pose no danger to humans. They belong to a group of insects know as the Homopterans, which include other insects like treehoppers, leafhoppers and spittlebugs. The loud songs produced by male cicadas are notorious and are specific to each species. These sounds may come from abdominal contortions or wing-banging. Periodical cicadas are may be referred to as "17-year locusts." Early American colonists had never seen periodical cicadas. They were familiar with the biblical story of locust plagues in Egypt and Palestine, but were not sure what kind of insect was being described. When the cicadas appeared by the millions, some of these early colonists thought a "locust plague" had come upon them. Some American Indians thought their periodic appearance had an evil significance. The confusion between cicadas and locusts exists today in that cicadas are commonly called locusts. The term "locust" is correctly applied only to certain species of grasshoppers. There are six species of periodical cicadas, three with a 17-year cycle and three with a 13-year cycle. The three species in each life-cycle group are distinctive in size, color, and song. The 17-year cicadas are generally northern, and the 13-year cicadas southern with considerable overlap. In fact, both life-cycle types may occur in the same forest (but emerge together every 221 years).

Economically, it is chiefly important in the adult stage from the likelihood of its injuring nursery stock and young fruit trees by depositing its eggs.

  • Avian Predators Are Less Abundant During Periodical Cicada Emergences, but Why?

KOENIG, LESLIE RIES, V. BETH K. OLSEN, AND ANDREW M. LIEBHOLD 1Lab of Ornithology and Department of Neurobiology and Behavior, Cornell University, 159 Sapsucker Woods Road, Ithaca, New York 14850 USA 2Department of Biology, University of Maryland, College Park, Maryland 20742 USA 3USDA Forest Service Northern Research Station, 180 Canfield Street, Morgantown, West Virginia 26505 USA Abstract. Despite a substantial resource pulse, numerous avian insectivores known to depredate periodical cicadas (Magicicada spp.) are detected less commonly during emergence years than in either the previous or following years. We used data on periodical cicada calls collected by volunteers conducting North American Breeding Bird Surveys within the range of cicada Brood X to test three hypotheses for this observation: lower detection rates could be caused by bird calls being obscured by cicada calls (‘‘detectability’’ hypothesis), by birds avoiding areas with cicadas (‘‘repel’’ hypothesis), or because bird abundances are generally lower during emergence years for some reason unrelated to the current emergence event (‘‘true decline’’ hypothesis). We tested these hypotheses by comparing bird detections at stations coincident with calling cicadas vs. those without calling cicadas in the year prior to and during cicada emergences. At four distinct levels (stop, route, range, and season), parallel declines of birds in groups exposed and not exposed to cicada calls supported the true decline hypothesis. We discuss several potential mechanisms for this pattern, including the possibility that it is a consequence of the ecological and evolutionary interactions between predators of this extraordinary group of insects.

MARSHALL1,3) (Department of Biology and Museum of Zoology, University of Michigan, Ann Arbor, MI 48109-1079) (Acc. 4-VI-2001) Summary Periodical cicada (Magicicada spp.) sexual pair formation takes place in dense aggregations and involves intense male-male competition for limited mating opportunities. Pair-forming behavior in these species has been poorly understood because of limited knowledge of sexual communication. We have found that sexually receptive female Magicicada ick their wings in timed response to an individual chorusing male; this previously unrecognized female response is hereafter referred to as a ‘wing- ick’ signal. We document the nature, timing, and species-speci city of this signal as well as its absence in both immature and mated females. We also document changes in male chorusing and searching behavior in response to wing- ick signals and male responses to the signals’ visual and acoustical components. We test the hypothesis that female sensory psychology has shaped the evolution of -decim calls by 1) Current address: Department of Ecology and Evolutionary Biology, University of Connecticut, 75 North Eagleville Road, Storrs CT 06269-3043. 2) Corresponding author; e-mail address: [email protected] 3) We thank R.D.
