Good morning, everyone. Today we're going to discuss the impact of urbanization on local wildlife. A recent study in Manchester found that while some bird species, like pigeons and sparrows, have adapted well to city life, others, such as the song thrush, have declined by over 60% in the last decade. Interestingly, the presence of small gardens and parks in residential areas has been linked to a slower decline. The study also highlighted that noise pollution affects birds' ability to communicate, leading to changes in their singing patterns. However, the most surprising finding was that artificial lighting at night disrupts the migration of insects, which in turn affects the birds that feed on them.
❓ ¿Cuál fue el hallazgo más sorprendente del estudio mencionado en la conferencia?
A. A) El declive de los zorzales comunes en las áreas urbanas.
B. B) El impacto de la contaminación acústica en la comunicación de las aves.
C. C) El efecto de la iluminación artificial en la migración de los insectos.
