Mountain chickadees rely on spatial memory to forage in unpredictable environments and on song to defend their territories. Watch #ProcB author Sofia Haley talk about research that suggests overall song output may be an indicator of cognitive ability: cassyni.com/events/Mw4c4... #ecology

Why do we not see evolutionary change in heritable, fitness-related traits in free-living populations? @erikpostma.bsky.social &co use the #evolution of clutch size in great tits to show the importance of gene flow in explaining contemporary evolutionary change and stasis 🧪 buff.ly/ngAKH6r
Scatter plot comparing individual breeding values at year t−1 and year t, with blue dots = survivors, orange dots = non‑survivors, green dots = native recruits and magenta triangles = immigrant recruits. The genetic change attributable to local adaptation (i.e., the net effect of breeder mortality and the recruitment of local-origin individuals) is represented by a grey dashed line, which differs from the total genetic change in the breeding population (solid black line) that additionally includes the contribution of immigrant recruitment.

We use the covariance reaction norm method (by @jsmartin.bsky.social) on 40 years of great tit data from Wytham Woods. The natal-to-adult body mass correlation in this population is high on average (r ≈ 0.7) but appears to vary with temperature, rainfall, and density, particularly during breeding.
(A,B) Illustrative plots of strong versus weak among-individual correlation between nestling mass and adult mass; each point represents an individual and the grey line is a linear fit shown for visual reference. (C) A schematic correlation reaction norm translating these two scenarios (A,B) onto a correlation-versus-environment axis; the y-axis
tracks how consistently natal body mass predicts adult mass. Curve shape is illustrative, and does not represent real data.Among-individual correlations between nestling mass and adult body mass of great tits from Wytham Woods, UK as functions of (A) adult population density (number of pairs of great tits and blue tits in the breeding year), (B) natal population density (number of pairs of great and blue tits in the hatch year), (C) adult temperature (average daily temperature in ºC during breeding), (D) natal temperature (average daily temperature in ºC during development i.e. 0–15 days post hatching), (E) adult rainfall (average daily rainfall in mm during breeding), (F) natal rainfall (average daily rainfall in mm during development i.e. 0–15 days post hatching); Lines show the posterior median effect sizes; shaded bands show 25–75%, 10–90%, and 5–95% credible intervals. Insets show the posterior distribution of the corresponding slope (point = posterior median; thick bar = 50% CI; thin bar = 90% CI; dashed line = zero).

Winter work shows it really pays to be a smart mountain chickadee
By studying chickadee cognition in the wild, researchers learned smarter birds stay smart in old age, produce more young and have better gut bacteria.

How animals sense Earth’s magnetic field is one of biology’s enduring mysteries. Researchers have now identified superparamagnetic macrophages in the livers of rock pigeons (Columba livia) to be crucial for magnetic sensing. The finding uncovers an unexpected role for immune cells in sensory perception and may fundamentally change our understanding of animal navigation.
