FAMIL YFRINGILLIDAE (GROSBEAKS, FINCHES, SPARROWS, AND BUNTINGS) . Cardinal Cardinal Cardinalis cardinalis (Richmondena cardinalis) Breeding Status: Breeds from the Red River Valley of southeast­ ern North Dakota (north to Cass County) southward through adjacent southwestern Minnesota, eastern South Dakota (north along the Missouri River at least to Dewey County), most of Nebraska (west to Cherry, Thomas, and Deuel counties), eastern Colorado (at least to Morgan County), virtually all of Kansas (local and infrequent west of Seward, Hamilton, and Cheyenne counties), Oklahoma (west locally at least to Texas County), and the eastern panhandle of Texas (west at least to Potter County), The northern range limits of this species have expanded consider­ ably in this century (Wilson Bulletin 68: 111-17). Breeding Habitat: The species is associated with forest edges or brushy forest openings, parks and residential areas planted to shrubs and low trees, and second-growth woods, and with river bottom gallery forests in grasslands. Nest Location: Nests are usually 3-8 feet (rarely to 40 feet) in dense shrubbery, small trees, vines, or briar thickets. The nest is constructed of twigs, vines, and other materials in a loose cup, lined with fine grasses and hair. The nests are usually well con­ cealed in forks or in mats of vine stems but at times are placed very close to human traffic patterns. Clutch Size and Incubation Period: From 3 to 6 eggs (65 Kansas clutches averaged 3.5). The eggs are grayish to bluish white, with brown dots, spots, and blotches varying greatly in extent. The incubation period is 12-13 days. Regularly multiple-brooded in our region. Time of Breeding: Nests with eggs have been found in North Dakota and Minnesota from late April to early June. In Kansas the range of egg dates is from April 1 to September 20, with a peak in initial clutches about May 1, followed by asynchronous breeding through the summer. Texas egg records extend from March 3 to July 31. Breeding Biology: Pair bonds are probably fairly permanent in this relatively sedentary species, and toward the end of winter males show such signs of the reawakening of sexual behavior as tolerating females on the same feeding platform and sometimes directly feeding them. Territorial display begins early; the males sing in prominent locations and chase other males away. Thus non breeding assemblages gradually break up, and females begin to seek out suitable nest sites. The female usually builds the nest alone, over a period of 3 to 9 days, and lays the first egg within a week of its completion. Normally the female incubates alone, although at times males have been observed sitting on the nest._ Both parents feed the nestlings, which leave the nest in 7-11 days 447 and are able to fly well by the time they are 19 days old. By about 45 days the young are completely independent of their parents, which by then have usually begun another brood. At least three broods are commonly raised in a season, and in some areas as many as four are fairly common. Suggested Reading: Laskey 1944; Bent 1968. Rose-breasted Grosbeak Pheucticus ludovicianus Breeding Status: Breeds in western Minnesota and eastern North Dakota to the Souris River and rarely the Missouri River (Wi/son Bulletin 85:230-36), southward through eastern South Dakota west at least to Todd County (Wi/son Bulletin 85: I-II), eastern Nebraska west to Garfield and Buffalo counties (Nebraska Bird Review 29: 19), eastern Kansas west locally to Rawlins County (Rising 1974), and eastern Oklahoma (west locally at least to Kay and Cleveland counties). Hybridization with the black-headed grosbeak makes the western limits of this species rather difficult to define (Auk 79:399-424). Breeding Habitat: The species is associated with relatively open deciduous forests on floodplains, slopes, and bluffs. The relative development of the understory is apparently not particularly important in this species (Wi/son Bulletin 86:7). Nest Location: In a South Dakota study, most grosbeak nests (both species) were 10-19 feet above the ground, and box elders "==:W~~ were favored nesting trees. More generally the forks and crotches of various deciduous trees are used, and the nest is poorly con­ structed of twigs and grasses, lined with fine twigs and rootlets. Clutch Size and Incubation Period: From 3 to 5 eggs (6 North Dakota nests averaged 3.8). The eggs are pale grayish to bluish, with dark brownish spots and blotches around the larger end, often forming a cap or wreath. The incubation period is 12-14 days. Usually single-brooded; double-brooding is reported in semicaptive birds. Time of Breeding: North Dakota egg dates.are from May 31 to June 27. In Kansas, eggs have been reported from May 11 to July 11, with a probable peak of laying in early June. Breeding Biology: Immediately after the males return to their breeding areas in spring, they establish territories and begin to announce them with a warbled song and aggressive encounters with other males. Females arrive a few days later and are initially chased aggressively by males. Soon the male stops chasing the female, and she may attack him instead. Courtship feeding of the female is apparently uncommon in this species. The female builds 448 the nest with the help of the male, and the male regularly partici- pates in incubation. Both sexes care for the young, and at least in two cases the males have been known to take over the care of young birds while the female began a second nesting. The young remain in the nest 9-12 days. Suggested Reading: Dunham 1966; Bent 1968. Black-headed Grosbeak Pheucticus me/anocepha/us Breeding Status: Breeds in western North Dakota east to the Missouri River and rarely to the Souris River, in western South Dakota east at least to Charles Mix County, and occurs as hy­ brids to Clay County (Wilson Bulletin 86:5), in Nebraska east­ ward locally to at least Rock, Garfield, and Hall counties (Ne­ braska Bird Review 29:19), in northwestern Kansas (east locally or sporadically at least to Cloud and perhaps Sedgwick counties, but mostly confined to the northwestern counties), and northeast­ ern Colorado (at least the Platte Valley). The only other breeding record for our region seems to be Quay County, New Mexico. Eastern limits of breeding are confused by frequent hybridization with the rose-breasted grosbeak (Auk 79:399-424; Wilson Bul­ letin 85:230-36). Breeding Habitat: The species is associated primarily with rela­ tively open stands of deciduous forest in floodplains or uplands, especially those with well-developed understories. Also found secondarily in orchards, brushy woodlands or chaparral, and parks or suburbs with many trees. Nest Location: The nest location and nest structure of this species seems to be identical to that of the rose-breasted grosbreak. Nests average about 10 feet above the ground and are usually in crotches or forks of horizontal or vertical branches of deciduous trees. The nest is a bulky structure of slender twigs, stems, and rootlets, lined with rootlets and fine stems. Clutch Size and Incubation Period: From 2 to 5 eggs, usually 3 or 4. The eggs are not distinguishable from those of the rose­ breasted grosbeak. The incubation period is 12 days. Probably single-brooded. Time of Breeding: The probable breeding season in North Da­ kota extends from late May to late July. In Kansas the egg records are from May 11 to July 10, with a peak of egg-laying in early June. Breeding Biology: So far as is known, the breeding biology of this species is essentially identical to that of the rose-breasted gros­ beak. Studies of these two closely related forms in North Dakota indicate that the courtship behavior of the two is very similar, and 449 thus the color differences among the males are likely to be impor­ tant in avoiding more widespread hybridization than occurs. Males apparently do not discriminate between the songs of their own and the other species, but do make visual discriminations when confronted with mounted males placed in their territories. Suggested Reading: Weston 1947; Kroodsma 1970. Blue Grosbeak Guiraca caerulea (Passerina caerulea) Breeding Status: Breeds from central South Dakota (north at least to Haakon and Dewey counties, Nebraska Bird Review 29: 11) southward through virtually all of Nebraska (local in east), western Iowa (uncommonly), northwestern Missouri (occa­ sionally), Kansas (increasingly common to west), eastern Colo­ rado (uncommonly), Oklahoma (throughout), northern Texas and northeastern New Mexico. Breeding Habitat: The species is associated with weedy pastures, old fields growing up to saplings, forest edges, streamside thick­ ets, and hedgerows. Nest Location: Nests are placed 3-12 feet high in a variety of shrubs, small trees, vines, and so forth, usually at the edge of a clearing.

  • A COMPARATIVE ANALYSIS of SONG and RESPONSES to SONG PLAYBACK University of Colorado at Denver
    FINAL REPORT A COMPARATIVE ANALYSIS OF SONG AND RESPONSES TO SONG PLAYBACK IN THE AVIAN GENUS PIPILO Peter S. Kaplan Department of Psychology University of Colorado at Denver Abstract An experiment was undertaken to characterize the responses of Green-tailed Towhees (Pipilo chlorura) and Rufous-sided Towhees (P. erythophthalmus) to each others' songs and to the songs of five other towhee species, plus one hybrid form. A total of 12 Green-Tailed Towhees and 10 Rufous-sided Towhees from Boulder and Gilpin counties were studied at three field sites: the Doudy Draw Trail, the National Center for Atmospheric Research (NCAR), and on private land at the mouth of Coal Creek Canyon. In May, each bird was mist-netted and banded to facilitate individual identification. During the subsequent playback phase in June and July, each individual received one three-part playback trial on each of 7 consecutive or near-consecutive days. A 9-min playback trial consisted of a 3-min "pre-play" period, during which the bird was observed in the absence of song playback, a 3-min "play" period, in which tape recorded song was played to the subject from a central point in his territory, and a 3-min "post-play" period when the bird • was again observed in the absence of song playback. Order of presentation of song exemplars from different towhee species were randomized across birds. The main dependent measure was the change in the number of songs produced by the subject bird during song playback, relative to the pre-play period. Results showed that Green-tailed Towhees responded by significantly increasing their rate of singing, but only in response to Green-tailed Towhee songs.

  • Wildland Fire in Ecosystems: Effects of Fire on Fauna
    United States Department of Agriculture Wildland Fire in Forest Service Rocky Mountain Ecosystems Research Station General Technical Report RMRS-GTR-42- volume 1 Effects of Fire on Fauna January 2000 Abstract _____________________________________ Smith, Jane Kapler, ed. 2000. Wildland fire in ecosystems: effects of fire on fauna. Gen. Tech. Rep. RMRS-GTR-42-vol. 1. Ogden, UT: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 83 p. Fires affect animals mainly through effects on their habitat. Fires often cause short-term increases in wildlife foods that contribute to increases in populations of some animals. These increases are moderated by the animals’ ability to thrive in the altered, often simplified, structure of the postfire environment. The extent of fire effects on animal communities generally depends on the extent of change in habitat structure and species composition caused by fire. Stand-replacement fires usually cause greater changes in the faunal communities of forests than in those of grasslands. Within forests, stand- replacement fires usually alter the animal community more dramatically than understory fires. Animal species are adapted to survive the pattern of fire frequency, season, size, severity, and uniformity that characterized their habitat in presettlement times. When fire frequency increases or decreases substantially or fire severity changes from presettlement patterns, habitat for many animal species declines.

  • Voice in Communication and Relationships Among Brown Towhees
    THE CONDOR VOLUME 66 SEPTEMBER-OCTOBER, 1964 NUMBER 5 VOICE IN COMMUNICATION AND RELATIONSHIPS AMONG BROWN TOWHEES By JOET.MARSHALL,JR. This paper seeks to answer two questions: (1) What is the function of each song and call in brown towhees; that is, what information does a bird communicate to its fellows vocally, o’r how does it regulate their behavior by its voice? (2) What evi- dence does voice offer for understanding relationship by descent within the closely-knit group of brown towhee species? For the first, I would extend the analysis of Quain- tance (1938,194l) to all members of the group. As to the second question, an ingenious evolutionary reconstruction, based on museum and habitat studies, has been developed by Davis (1951). Do vocal attributes agree with his scheme? The three speciesof brown towhees, genus Pipdo, are the same size and general color and are more similar to each other than any one of them is to other ground-inhabiting finches in the same genus and in the genus Melozorte. Indeed, so close is their relation- ship that the same calls can easily be discerned in each species; although differing in timbre, similarity in form and usage proclaims them to be homologous. The Abert Towhee (Pipdo abed) occupies dense riparian woodland and mesquite thickets of the Colorado River and Gila River drainages, mostly in Arizona. The Brown Towhee proper (Pip20 fuscus) lives in brushy margins of openings in the southwestern United States and Mexico. The White-throated Towhee (Pipilo aZbicoZZis)inhabits brushy slopes, often with tree yuccas, in Puebla and Oaxaca, MCxico.

  • 18 February 2015 – JB Invertebrates the Purpose of This Lab Is to Gain
    18 February 2015 – JB Invertebrates The purpose of this lab is to gain a better understanding of the complexity of invertebrates. The simplest invertebrates are sponges in the Porifera phylum. The rest of invertebrates have more complex tissue. Some of those have radial symmetry, meaning circular symmetry, and others have bilateral symmetry, meaning symmetrical from left to right. Invertebrates that live in the soil are called Anthropods, which is what we studied in this experiment. Most are very small, so they are classified as microanthropods. In this lab we first observed three types of worms, acoelomats, pseudocoelomates, and coelmates under a microscope; noting the complexity of their shape and movement. We then observed an organism from each of the five major classes: arachnida, diplopoda, chilopoda, insect, and crustacean. We observed their body parts, body segments, and the number of appendages. We then analyzed the invertebrates that we collected with our Berlese Funnel. We poured some of the sample into two separate petri dishes, one dish being the top of our liquid sample, and the other dish being the bottom. Then we observed and identified the anthropods found in the dish. Lastly, we drew conclusions about the types of invertebrates that might inhibit transect one, the marsh.
