Types of Birds Commonly Identified as Pests and Why

Birds are often celebrated for their beauty and ecological importance, but certain species can become problematic when they invade human spaces. In Nairobi and across Kenya, several bird species are classified as pests due to their disruptive behaviors, health risks, and damage to property. Understanding which birds are considered pests and why is crucial for effective pest control. This article by PestPro explores the most common pest birds in Kenya, the reasons they are problematic, and how professional pest control services can help manage them.

What Makes a Bird a Pest?

Birds are labeled as pests when their activities negatively impact human health, safety, or property. Common issues include:

• Health Risks: Bird droppings can spread diseases such as histoplasmosis, salmonellosis, and psittacosis.
• Property Damage: Nests, droppings, and pecking can damage buildings, vehicles, and crops.
• Noise Pollution: Excessive chirping or squawking can disturb residents and businesses.
• Food Contamination: Birds in food storage or preparation areas pose hygiene risks.
• Aggressive Behavior: Some birds may attack humans or pets when protecting their nests.

In Kenya, urban and rural environments provide ideal conditions for certain bird species to thrive, often leading to conflicts with humans. Below, we discuss the most common pest birds and why they are problematic.

Common Pest Birds in Kenya

1. Pigeons (Columba livia)

Pigeons, often called "flying rats," are among the most widespread pest birds in Nairobi and other Kenyan cities.

• Why They Are Pests:
  • Health Risks: Their droppings carry pathogens that can cause respiratory diseases like histoplasmosis.
  • Property Damage: Acidic droppings corrode metal, paint, and building surfaces. Nests clog drains and gutters.
  • Food Contamination: Pigeons frequent food markets and warehouses, contaminating goods.
  • Urban Nuisance: Large flocks create noise and mess in public spaces like markets and bus stations.
• Common Habitats: Urban areas, rooftops, ledges, and public squares.

2. House Sparrows (Passer domesticus)

House sparrows are small but highly adaptable birds found throughout Kenya, particularly in residential and commercial areas.

• Why They Are Pests:
  • Crop Damage: Sparrows feed on grains, fruits, and vegetables, causing losses for farmers.
  • Nesting Issues: Their nests in vents, eaves, and machinery can cause blockages or fire hazards.
  • Competition: They outcompete native birds for food and nesting sites, disrupting ecosystems.
  • Food Contamination: Sparrows invade restaurants and food stores, posing hygiene risks.
• Common Habitats: Gardens, markets, warehouses, and homes.

3. Indian House Crows (Corvus splendens)

Indian house crows are highly intelligent and invasive birds that have become a significant pest in Kenya, especially in coastal and urban areas.

• Why They Are Pests:
  • Aggressive Behavior: Crows attack smaller birds, steal food, and occasionally harass humans or pets.
  • Health Risks: Their droppings and scavenging habits spread diseases and contaminate water sources.
  • Crop and Property Damage: They raid crops, scatter garbage, and damage electrical wiring.
  • Noise Pollution: Their loud cawing disrupts homes and businesses.
• Common Habitats: Urban centers, dumpsites, and coastal towns like Mombasa.

4. Weavers (Ploceus spp.)

Weaver birds, known for their intricate nests, are common in both rural and urban Kenya but can become pests in certain contexts.

• Why They Are Pests:
  • Crop Damage: Weavers feed on cereal crops like maize and sorghum, causing significant agricultural losses.
  • Nesting Problems: Their large, woven nests in trees or on power lines can cause structural damage or power outages.
  • Noise: Colonies of weavers create considerable noise, disturbing nearby residents.
• Common Habitats: Farmlands, gardens, and suburban areas.

5. Starlings (Sturnus vulgaris)

Starlings, particularly the common starling, are invasive birds that thrive in Kenyan towns and agricultural areas.

• Why They Are Pests:
  • Agricultural Damage: They consume and damage fruits, grains, and livestock feed.
  • Nesting Issues: Nests in building cavities or vents lead to blockages and sanitation problems.
  • Disease Transmission: Droppings can harbor fungi and bacteria harmful to humans.
  • Competition: Starlings displace native bird species, affecting biodiversity.
• Common Habitats: Farms, orchards, and urban rooftops.

6. Egrets (Egretta spp.)

Cattle egrets and other egret species are often considered pests in rural and peri-urban areas of Kenya.

• Why They Are Pests:
  • Crop Damage: Egrets forage in rice paddies and other crops, trampling plants and eating seeds.
  • Nuisance in Urban Areas: Large flocks roost in trees or on buildings, leaving droppings that deface property.
  • Noise: Their calls and flapping can disturb residents, especially at night.
• Common Habitats: Wetlands, farmlands, and urban parks.

Why Professional Bird Control Is Essential

Managing pest birds requires a strategic approach to minimize harm to the birds, humans, and the environment. DIY methods, such as traps or poisons, can be ineffective, inhumane, or illegal under Kenya’s Wildlife Conservation and Management Act. Professional pest control services like PestPro offer:

• Humane Solutions: We use deterrents like netting, spikes, and sound devices to prevent birds from roosting without harming them.
• Targeted Strategies: Our technicians assess the species and behavior to design customized control plans.
• Compliance with Regulations: We adhere to guidelines from the Kenya Wildlife Service (KWS) and Pest Control Products Board (PCPB).
• Sanitation and Prevention: We clean up droppings and nests safely and implement measures to prevent re-infestation.
• Integrated Pest Management (IPM): We combine physical, biological, and chemical methods for long-term control.

Prevention Tips for Homeowners and Businesses

To reduce the risk of pest bird problems, consider the following:

• Seal Entry Points: Install screens or seal gaps in roofs, vents, and eaves to prevent nesting.
• Manage Waste: Secure garbage bins and clean food spills to avoid attracting birds.
• Install Deterrents: Use bird spikes, reflective tape, or netting to discourage roosting.
• Maintain Landscaping: Trim trees and shrubs near buildings to reduce nesting sites.
• Regular Inspections: Schedule professional inspections to catch early signs of bird activity.

Pigeons, house sparrows, Indian house crows, weavers, starlings, and egrets are among the most common pest birds in Kenya, causing health risks, property damage, and economic losses. Their adaptability to urban and rural environments makes them challenging to control without professional help.
