“…In redwinged blackbirds, Agelaius phoeniceus, females do not discriminate between the songs of other females (Beletsky, 1983a), while males do discriminate between their mate's song and another female's song (Beletsky, 1983b). In black-capped chickadees, a previous neurobiological study found more immediate early gene expression in male birds presented with male songs compared to female songs, but no difference in gene expression for female birds presented with male or female songs (Avey et al, 2008), indicating a sex difference in the perception of male and female songs.…”

“…Recently it was reported that both male and female blackcapped chickadees produce songs (Hahn, Krysler, & Sturdy, 2013) and that these songs induce different amounts of immediate early gene expression, depending on the sex of the bird producing the song and the sex of the bird hearing the song (Avey, Kanyo, Irwin, & Sturdy, 2008). Black-capped chickadee songs are a relatively simple two-note, tonal signal called the fee-bee song and the songs produced by males and females contain overall structural similarity (i.e.…”

“…Gentner et al (2001) introduced the practice of dividing NCM into dorsal and ventral domains by bisecting it orthogonal to its dorso-ventral axis. Since that time, the majority of published studies have followed this convention (e.g., Eda-Fujiwara et al, 2003;Maney et al, 2003;Phillmore et al, 2003;Hernandez and MacDougall-Shackleton, 2004;Avey et al, 2005Avey et al, , 2008Sockman et al, 2005;McKenzie et al, 2006;Tomaszycki et al, 2006;Lynch and Ball, 2008;Sockman and Salvante, 2008;Velho and Mello, 2008). Although many researchers have reported that dorsal and ventral NCM differ in their sensitivity to and selectivity for a variety of experimental stimuli, these domains do not appear to have a cytoarchitectonic, neurochemical, or hodological basis.…”

“…Throughout most of its extent, its responses to sound are organized tonotopically Terleph et al, 2006), and the zenk response to song is generally more robust in the dorsomedial aspect than the ventrolateral aspect (Gentner et al, 2001;Maney et al, 2003;Phillmore et al, 2003;Terpstra et al, 2004;Sockman et al, 2005;Avey et al, 2008;Lynch and Ball, 2008;Vignal et al, 2008;Sockman and Ball, 2009;cf.

Topography of estradiol‐modulated genomic responses in the songbird auditory forebrain

Sex steroids facilitate dramatic changes in behavioral responses to sociosexual signals and are increasingly implicated in the sensory processing of those signals. Our previous work demonstrated that in female white-throated sparrows, which are seasonal breeders, genomic responses in the auditory forebrain are selective for conspecific song over frequency-matched tones only when plasma estradiol (E2) reaches breeding levels. Here, we sought to map this E2-dependent selectivity in the best-studied area of the auditory forebrain, the caudomedial nidopallium (NCM). Nonbreeding females with low endogenous levels of E2 were treated with E2 or a placebo and exposed to conspecific song, tones, or no sound playback. Immunoreactive protein product of the immediate early gene zenk (egr-1) was then quantified within seven distinct subregions, or domains, of NCM. We report three main findings: (1) regardless of hormone treatment, the zenk response is significantly higher in dorsal than in ventral NCM, and higher in medial than in lateral NCM; (2) E2-dependent selectivity of the response is limited to the rostral and medial domains of NCM; in the more caudal domains, song induces more zenk expression than tones regardless of hormone treatment; (3) even when no sound stimuli were presented, E2 treatment significantly increased zenk expression in the rostral, but not the caudal, domains of NCM. Together, the latter two findings suggest that E2-dependent plasticity in NCM is concentrated in rostral NCM, which is hodologically and neurochemically distinct from caudal NCM. Activity in rostral NCM may therefore be seasonally regulated in this species.

“…All the members of this closely related group of species [22] use a complex call (the namesake chick-a-dee call [23], [24]). Studies of CMM and NCM in black-capped chickadees have revealed robust ZENK expression in response to their tonal conspecific fee-bee song and acoustically complex chick-a-dee call [25], [26]. In this study, we tested how phylogenetic and acoustic similarity influences the neural responses of CMM and NCM to conspecific and heterospecific calls in black-capped chickadees.…”

ZENK Activation in the Nidopallium of Black-Capped Chickadees in Response to Both Conspecific and Heterospecific Calls

Neuronal populations in the songbird nidopallium increase in activity the most to conspecific vocalizations relative to heterospecific songbird vocalizations or artificial stimuli such as tones. Here, we tested whether the difference in neural activity between conspecific and heterospecific vocalizations is due to acoustic differences or to the degree of phylogenetic relatedness of the species producing the vocalizations. To compare differences in neural responses of black-capped chickadees, Poecile atricapillus, to playback conditions we used a known marker for neural activity, ZENK, in the caudal medial nidopallium and caudomedial mesopallium. We used the acoustically complex ‘dee’ notes from chick-a-dee calls, and vocalizations from other heterospecific species similar in duration and spectral features. We tested the vocalizations from three heterospecific species (chestnut-backed chickadees, tufted titmice, and zebra finches), the vocalizations from conspecific individuals (black-capped chickadees), and reversed versions of the latter. There were no significant differences in the amount of expression between any of the groups except in the control condition, which resulted in significantly less neuronal activation. Our results suggest that, in certain cases, neuronal activity is not higher in response to conspecific than in response to heterospecific vocalizations for songbirds, but rather is sensitive to the acoustic features of the signal. Both acoustic features of the calls and the phylogenetic relationship between of the signaler and the receiver interact in the response of the nidopallium.
