Final decisionswill be made by the Council of The Wilson Ornithological Society at the annual meeting of the Society, 12-15 April 1979. INDIVIDUAL AUDITORY RECOGNITION IN THE LEAST TERN (STERNA ALBIFRONS) LYNN J. MOSELEY• Department of Zoology, University of North Carolina, Chapel Hill, North Carolina 27514 USA ABST•CT.--Playback experiments performed in a colony of Least Terns near Fort Macon, North Carolina, demonstrated that adults can distinguish the call of their mate from that of a stranger. Sonagram analysis of the "Purrit-tit-tit" call, the most common vocalization used when an adult approachesits mate, revealed that both temporal and spectral characteristicsof the first note of the call varied significantly among individuals, whereas all measured features of the second note were not significantlydifferent for different birds. Presumably the first note is used to convey an individual's identity, while the secondnote indicates a tendency to approach the mate and perform certain courtship behaviors. Received 17 January 1978, accepted26 March 1978. IN his review of individual auditory recognition in birds, Beer (1970a) stated that the best evidence for the existenceof vocal recognition comeseither from colonial species, for which the omnidirectional properties of sound far exceed those of visual signals in a crowded colony, or from speciesthat inhabit thick vegetation, as foliage obstructsvision but doesnot greatly hinder sound transmission. This study examines vocal recognition between mates in the Least Tern (Sterna albifrons), a colonially- nesting larid. Individual recognition by voice has been hypothesized for several speciesof co- lonial birds and documentedfor a few. Most investigationsdeal with auditory com- munication between members of a mated pair or between parent birds and their young. According to Beer, investigators have used three approachesin the study of vocal recognition in birds: field observation, sound analysis, and playback experi- ments. Field observation has provided circumstantial evidence for the existence of auditory recognition between mates in several colonial species(e.g. Sterna hirundo, Tinbergen 193! and Palmer 194!; Larus argentatus, Tinbergen !953) and between parents and offspring (e.g.S. fuscata, Watson and Lashley 1915; L. argentatus, Goethe 1937; S. sandvicensis, Hutchinson et al. 1968). However, some method of experimentation is usually necessaryto eliminate the possibility that a bird is actually respondingto visual rather than auditory stimuli, as in most casescolonial birds can see as well as hear one another (Beer 1970a). Several investigators have performed experiments to test the ability of parent birds to recognizetheir own chicks. Although individual recognitionof chicks has been demonstratedfor several speciesof colonial nesters(e.g. Anous stolidus and S. fuscata, Lashley 1913; S. bergii, Davies and Carrick 1962; S. maxima, Buckley and Buckley 1972), such experiments usually do not reveal the relative importance of visual and auditory modalitiesfor suchrecognition. However, Miller and Emlen's (1974) study of the effect of altering a chick'svoice and appearanceon the recognition of young by their parents in the Ring-billed Gull (Larus delawarensis)revealed that vocally impaired chicks 12 to 20 days old were accepted whereas visually altered chicks were not. In some species, at least, visual rather than auditory stimuli are important for the development of chick recognition. Experiments involving the recognitionof parents' voices by chicks have met with somewhat more successdue to the ease with which chicks can be manipulated. Presentaddress: Department of Biology,Guilford College, Greensboro, North Carolina27410 USA. 31 The Auk 96: 31-39. January 1979 32 LYNN J. MOSELEY [Auk, Vol. 96 Controlled playback experiments, performed under both natural and laboratory conditions, demonstrate that in most cases chicks of colonial species clearly distin- guish between the voice of a parent and the voice of a strange adult (Uria aalge, Tschanz 1968; L. atricilla, Beer 1969, 1970b; S. hirundo, Stevenson et. al. 1970). White (1971) reported that chicks of the Gannet (Sula bassana) seem to have the ability to recognize the voice of a parent in a playback test, but do not always do so. Presumably in this speciesthere is no particular advantage for vocal recognition between parents and young since, unlike the specieslisted above, Gannet chicks are not mobile and remain on the nest until fledging. Investigators have also studied the ability of adult birds to discriminate the call of the mate from that of other adults in the colony. Hutchinson et. al. (1968) recorded "fish calls" from 40 adult Sandwich Terns (S. sandvicensis) and analyzed various temporal and spectral parameters of sonagramsof these calls. They concludedthat the general "patterning" of the call was always characteristic for each individual. However, they were unable to perform playback experiments to test whether the adults did, in fact, use such characteristicsto identify their mates by voice. They were also unable to record more than one sequence of vocalizations from each individual. Intra-individual variation is probably greater among calls from different sequencesthan among calls in the same sequence(see below). In a more conclusive investigation, playbacks showedthat adult Gannets recognizevocalizations of their mates (White 1971). Sonagram analysis of landing calls of individual Gannets sug- gested that recognition resulted from individually consistent temporal changes in amplitude (White and White 1970). To demonstrate individual auditory recognition, playback experiments must show that test birds respond selectivelyto vocalizationsfrom different individuals. Anal- ysis of physical characteristicsof the vocalization should reveal one or more sources of interindividual variation. Using this procedure, I investigated auditory recogni- tion between mates in Least Terns.

  • 6.5 Coastal Cactus Wren (Campylorhynchus Brunneicapillus Sandiegensis) – Category SO Management Units with Known Occurrences
    Volume 2D: Goals and Objectives for Species Focus Management Species 6.0 Birds 6.5 Coastal Cactus Wren (Campylorhynchus brunneicapillus sandiegensis) – Category SO Management Units with Known Occurrences Coastal cactus wrens are restricted to cactus-dominated coastal sage scrub habitats in Southern California, from Ventura south to San Diego County and inland to western San Bernardino and western Riverside Counties. These wrens differ ecologically from more common desert wrens in the southwestern United States and northern Mexico. Coastal cactus wrens began significantly declining in San Diego County in the early 1980s due to habitat loss to agriculture and urban development (Rea and Weaver 1990). By 1990 there was a 33% population decline from the previous decade as a result of the loss of coastal birds and smaller populations, and a decline in abundance of remaining populations. Coastal cactus wren surveys and cactus mapping were implemented on Conserved Lands in the MSPA in 2009 and 2011 (USFWS 2011). Cactus wrens were documented on Conserved Lands in MUs 1, 2, 3, 4, 5, and 6 (see Occurrence Table and online map: http://arcg.is/2kU1bka). A range-wide genetics and banding study was conducted across occupied cactus scrub habitats in 2011–2013 by USGS to determine coastal cactus wren population genetic structure, connectivity, and genetic diversity in Southern California (Barr et al. 2015). The study found 3 main genetic clusters in San Diego County: Otay; San Diego/El Cajon (Sweetwater/Encanto/Lake Jennings); and San Pasqual. In the San Diego/El Cajon genetic cluster, wrens in the Sweetwater River watershed are connected to occurrences in Fletcher Hills and Lake Jennings to the northeast in MU4 and to occurrences in Encanto Canyon and other urban canyons to the west in MU2.

  • A Nesting of the Carolina Wren
    September194X Vol. 60, No. 3 THE WILSON BULLETIN 139 A NESTING OF THE CAROLINA WREN BY MARGARET M. NICE AND RUTH H. THOMAS1 HE Carolina Wren, Thryothorus ludovicianus, charming, conspicu- T ous, and widely distributed as it is throughout southeastern United States? has been much neglected by life-history students. And this in spite of the fact that it often leaves its characteristic woods habitat to nest about buildings and even on porches. In 1946 we were able to watch one nesting of this species from the arrival of the female to the leaving of the young. The male, which had been banded March 27, 1941, near North Little Rock, Arkansas, had lost a mate in late March 1946. On April 18 we noted him bringing three wisps of.grass and placing them under the eaves of the sleeping porch. (Typically, in Ruth Thomas’ experi- ence, a male does not build until mated.) On April 19 we first saw his new mate, an unbanded bird. BUILDING THE NEST In the afternoon of April 19, the new female came onto the porch, then flew to the base of a nearby oak; the male suddenly dropped down from his perch, hitting her and giving a loud song; she answered with the typical %creech” of the female Carolina. Later we discovered them nest-hunting in a shed to the south; we removed the grape bas- kets that were stored there and hung one (partially closed with a shingle) on the sleeping porch. The next morning (April 20)) at 7: 55, both came to the porch; they entered the basket, gave little notes, then left.
