Free‐living birds need to acquire enough food to fulfil their energetic needs, which may require more effort in habitats with less favourable conditions. Therefore, to maintain their necessary energy intake, birds need to adjust their foraging behaviour in response to varying habitat conditions.

Using over 416,000 occurrence records from 13 arthropod groups (6233 arthropod species), we mapped large‐scale richness patterns and identified biodiversity hotspots across the Iberian Peninsula and Balearic Islands. Hotspot congruence among arthropod groups was low, underscoring the importance of integrative, multi‐taxon approaches for conservation ...
