“…Instead, most referred to a top‐down effect limited to two trophic levels and focused on predator–prey dynamics 75 . Similar to our results, a previous study on biological control across different crop types (coffee crop, apple crop, vineyards) and agriculture types (traditional, organic, mixed) showed variation among pest abundance, crop damage, and yield, but the effect of avian regulation was positive in most cases despite higher disaggregation of moderator levels 76 …”

Following their argument, natural habitats could be sufficient in amount, proximity, composition, or configuration to provide large enough enemy populations for pest control.…”

Temperate climates exhibited a higher but non-significant effect size (Figure 3), which could be due to the marked seasonality that contributes to higher fluctuation of pest populations.…”

BACKGROUND: Birds have been shown to reduce pest effects on various ecosystem types. This study aimed to synthesize the effect of birds on pest abundance, product damage and yield in agricultural and forest systems in different environments. Our hypothesis is that birds are effective pest regulators that contribute to a reduction in pest abundance, enhancement of yield quality and quantity and economic profit, and that pest regulation may depend on moderators such as the type of ecosystem, climate, pest, and indicator (ecological or economic).RESULTS: We performed a systematic literature review of experimental and observational studies related to biological control in the presence and absence of regulatory birds. We retained 449 observations from 104 primary studies that were evaluated through qualitative and quantitative analyses. Of the 79 studies with known effects of birds on pest regulation, nearly half of the 334 observations showed positive effects (49%), 46% showed neutral effects, and very few (5%) showed negative effects. Overall effect sizes were positive (mean Hedges' d = 0.38 ± 0.06). A multiple model selection retained only ecosystem and indicator types as significant moderators.CONCLUSION: Our results support our hypothesis that there is a positive effect of avian control of pests for each analyzed moderator and this effect was significant for both ecological and economic indicators. Avian regulation of pests is a potential effective approach for environmentally friendly pest management that can reduce pesticide use regardless of the context of implementation.

“…Other vertebrate predators have long been known to use odor cues to find prey (Conover 2007, Gardiner and Atema 2007, Johannesen et al 2012. Recent work has shown that birds can also locate prey directly via odor cues (Nevitt 2000, Cunningham et al 2008, Saavedra and Amo 2018a, Amo and Saavedra 2021, Díaz-Siefer et al 2021. Predation on herbivorous insects is well known to be governed by tritrophic interactions mediated by the release of herbivore induced plant volatiles (HIPVs) upon plant wounding (D' Alessandro and Turlings 2006, Heil 2008, Arimura et al 2009, Kaplan 2012.…”

Insectivorous birds can provide ecological and economic services by decreasing pest populations in agricultural systems, but the magnitude of effect is often debated. We modeled the capacity for birds to suppress pest population growth using a common tropical coffee pest, the coffee berry borer (CBB) (Hypothenemus hampei) as a study system. Previous field experiments show that birds play a role in suppressing CBB infestations through predation, but the degree to which birds can suppress population growth enough to control infestations is unknown since CBB are only vulnerable to predators when gravid females disperse. Using previously published data on CBB life‐stage survivability, we constructed a female‐only, daily time‐step, deterministic Leslie matrix and projected CBB population growth for a single breeding season. Our goal was to assess the plausibility of CBB suppression by birds as a function of avian energy requirements, reported avian densities on coffee farms, prey composition of avian diets, estimated a caloric value of CBB, and the initial starting population size. Our model showed CBB population growth became exponential (λdaily = 1.042) and that at low, but not medium or high population sizes, were birds able to reduce population growth by 50%. In general, birds exert predation pressure on insect populations, but the ability to control infestations is complex, and is likely dependent on the initial CBB population size.
