## Abstract
<!-- 250 words max. Context, gap, method, key findings, implication. -->
[Example: Despite advances in acoustic monitoring, no study has quantified how urban noise affects bird call frequency in mid-sized European cities. We recorded 2,400 calls across Berlin, Vienna, and Prague over 18 months. Using spectral analysis and generalized linear mixed models, we found a 12% upward frequency shift in high-traffic zones. This suggests adaptive vocal plasticity but raises concerns about long-range communication degradation.]
## Introduction
CITE: Brumm et al. 2020 — urban noise and bird song frequency
CITE: Slabbekoorn & Ripmeester 2008 — birds adjust pitch to noise
The urban soundscape is changing faster than species can adapt. While prior work focused on tropical and North American contexts, European mid-sized cities remain understudied.
## Methods
METHOD: Recording protocol — 18 months, 3 cities, 800 calls each
METHOD: Spectral analysis — Raven Pro, FFT 1024, Hann window
METHOD: Statistical model — GLMM with city as random effect, traffic density as fixed effect
CITE: R Core Team 2023 — statistical computing environment
All recordings were taken between 05:00 and 08:00 during breeding season (April–July).
## Results
FINDING: 12% mean upward frequency shift in high-traffic zones (p < 0.001)
FINDING: No significant shift in low-traffic control zones
FINDING: Call amplitude increased by 3 dB in high-traffic areas
CITE: ggplot2 Wickham 2016 — visualization
Figure 1 shows the frequency distribution by traffic density quartile.
## Discussion
These findings align with Brumm et al.'s noise-dependent pitch-shift hypothesis but extend them to a novel geographic and climatic context. The amplitude increase suggests Lombard-effect-like compensation.
## Conclusion
Urban noise is driving measurable vocal adaptation in European passerines. Conservation planning must account for acoustic habitat quality, not just green space.
