Animals organize their time so that behaviors do not conflict with each other and align well environmental conditions. In species parental care, adults must also accommodate offspring needs into temporal allocation of resources activities. Avian parents face harsh constraints on budget during incubation, when they sustain themselves but transfer heat to eggs. During day-time, shuttling between incubating foraging is studied. At night, birds usually rest the nest provide stable incubation. However, stability night depends physiology conditions, its patterns consequences are poorly understood. We propose enhances chances embryos hatch might shorten incubation time, that, in an urbanizing world, may be compromised. recorded nocturnal restlessness, defined as variation temperature, by placing thermal loggers boxes urban (25 clutches) forest (70 great tits, where only females incubate. found increasing hatching success dropped ca. 60% per unit increase restlessness both habitats, despite higher forest. One putative driver unstable was artificial light at which for associated increased restlessness.

Artificial light at night (ALAN) is rapidly increasing and so scientific interest in its ecological evolutionary consequences. In wild species, ALAN can modify disrupt biological rhythms. However, experimental proof of such effects the still scarce. Here, we compared diel rhythms incubation behaviour, inferred from temperature sensors, female great tits (Parus major) breeding urban forest sites. parallel, simulated by mounting LED lights (1.8 lx) inside nest-boxes, to determine potentially causal role affecting patterns incubation. Urban females had an earlier onset activity females. Experimentally ALAN-exposed were similar their advanced activity, unexposed birds. exposed ALAN, but not females, more restless than control Our findings demonstrate that explain early timing incubating tits, on sleep disturbance are reflected Consequently, future research needs address potential ALAN-induced individual health, fitness population dynamics, particular populations previously affected pollution.

Behavioral traits are often the first response to changing environmental conditions, including human induced rapid change. For example, animals living in urban areas more aggressive than rural animals. This is especially evident songbirds; males of several species display elevated aggression habitats. Increased male has been associated with reduced parental care, but consequences this trade-off for males, social partners, and offspring context urbanization remains unclear. We explored effects increased on life history traits, outcomes song sparrows ( Melospiza melodia ). predicted that would reduce paternal investment result females providing greater nestling care or fledging success habitats compared rural. Contrary our prediction, did not decrease visited nest males. Additionally, birds had higher rural, though was largely due predation Our study among evaluate trade-offs expressed by adds a growing body evidence provide benefits some species.

Temperate-tropical comparisons of avian life history traits are helpful to understand the different selective pressures placed on birds by climate zones. Although there have been many comparative studies targeting multiple species in regions, few reproductive successes same between tropical and temperate regions.
