Song overlapping, noise, and territorial aggression in great tits

Behavioral Ecology, Год журнала: 2020, Номер 31(3), С. 807 - 814

Abstract Communication often happens in noisy environments where interference from the ambient noise and other signalers may reduce effectiveness of signals which lead to more conflict between interacting individuals. Signalers also evolve behaviors interfere with opponents, for example, by temporally overlapping them their own, such as song behavior that is seen some songbirds during aggressive interactions. Song has been proposed be a signal intent, but few studies directly examined association sender. In present paper, we whether are associated positively behaviors. We carried out simulated territorial intrusions population great tits (Parus major) living an urban–rural gradient assess signaling was negatively males displayed against intruder. This result inconsistent hypothesis this species. Ambient levels were did not correlate rate, duration, or overlapping. Great urban habitats display higher due either communication another indirect effect noise.

Urban resources limit pair coordination over offspring provisioning

Scientific Reports, Год журнала: 2020, Номер 10(1)

The amount of care parents provide to the offspring is complicated by an evolutionary conflict interest ('sexual conflict') between two parents. Recent theoretical models suggest that pair coordination provisioning may reduce this and increase parent fitness. Despite empirical studies showing common in avian species, it remains unclear how environmental ecological conditions might promote or limit ability coordinate care. We compared level coordination, measured as alternation synchrony nest visits, house wrens Troglodytes aedon pairs breeding a rural (10 nests) suburban (9 site investigated differences parental behaviours were related habitat composition, prey abundance they ultimately reproductive success. found alternated synchronized their visits more one. characterized fragmented with coniferous trees less caterpillar availability.

The importance of investigating the impact of simultaneous anthropogenic stressors: the effects of rising temperatures and anthropogenic noise on avian behaviour and cognition

Journal of Avian Biology, Год журнала: 2024, Номер 2024(11-12)

Rising temperatures and anthropogenic noise are two of the most pervasive well researched stressors affecting avian species globally. Despite often triggering similar behavioural responses in birds, frequently co‐occurring (particularly urban areas), impact these primarily investigated isolation. Here, we discuss compare commonly effects rising on behaviour. We then outline recent findings impacts cognition which underpins many adjustments. find that both high temperatures, when isolation, behaviours such as foraging, antipredator response, interactions with conspecifics. also can lead to cognitive impairment, but occurrence magnitude impairment varies depending trait examined. Finally, limited studies have simultaneously different scenarios additive, synergistic, or antagonistic may occur. hope our review will stimulate researchers investigate simultaneous other behaviour urban‐living wild birds.

Evidence that traffic noise increases territorial response in vermilion flycatchers

Frontiers in Ecology and Evolution, Год журнала: 2023, Номер 11

Опубликована: Авг. 1, 2023

Animals vocalize in particular ways noise, presumably to increase the probability of detection; however, this idea has been seldom put test. Vermilion flycatchers produce longer songs noisy territories. To test hypothesis that detection we ran a field playback experiment on 30 free-living males. Each male was exposed two treatments with same songs, but one treatment had traffic noise and other no noise. Half males were short (with four introductory elements – IE) half long (eight IE). If have higher expected experimental would little effect when heard larger they (i.e. significant interaction between song length treatment). We measured call flight responses, latencies fly, closest approach speaker. also ambient males’ territories evaluate possible association their responses. Males did not respond differently vs songs; more importantly, predicted found. Our results, do support are detected Interestingly, increased response as showed non-significant trend toward than without results strongly suggests amplifies territorial response, which may affect outcome competition.

Background noise but not urbanization level impacted song frequencies in an urban songbird in the Pearl River Delta, Southern China

Rapid urbanization has profoundly transformed habitats and increased noise pollution in urban environments. Elevated levels may mask acoustic signals of urban-dwelling organisms such as birds. Singing at higher frequencies is one typical responses to avoid this masking effect. However, high-frequency experience larger attenuation when transmitting open Here, we tested how elevated affect frequency characteristics song complexity the Oriental Magpie-robin (Copsychus saularis), a common songbird tropical Asia.

Our results showed that Magpie-robins sang minimum maximum noisier areas.

Taken together, our study adds growing publications illustrating phenotypes birdsongs have been changed anthropogenic soundscapes.

Social context and noise affect within and between male song adjustments in a common passerine

Behavioral Ecology, Год журнала: 2020, Номер 31(5), С. 1150 - 1158

Abstract Across populations, animals that inhabit areas with high anthropogenic noise produce vocalizations differ from those inhabiting less noisy environments. Such patterns may be due to individuals rapidly adjusting their songs in response changing noise, but individual variation is seldom explored. Therefore, we tested the hypothesis male house wrens (Troglodytes aedon) immediately adjust according and social context further modifies responses. We recorded songs, quantified defined within pairs as female fertile status between males number of conspecific neighbors. used a reaction-norm approach compare song trait intercepts (between-male effects) slopes (within-male function noise. Individuals adjusted duration How they achieved adjustments varied: some sang shorter others longer greater varied extent which duration. Variation could affected by competition between-male levels interacted neighbors affect syllable Neither within- nor effects were detected for frequency traits. Rather, mates lower-frequency increased peak more Among males, not frequency, whereas temporal structure depending on factors. Not all signals same way selection favor different
