Why do birds come to feeders on some days and not on others?

Table of Contents

Bird feeder activity fluctuates due to a combination of factors; simply put, birds visit feeders when they need supplemental food, and their needs change based on the season, weather, availability of natural food sources, and even predation risks. Understanding these influences provides insight into why do birds come to feeders on some days and not on others.

Understanding the Fluctuating Attendance at Bird Feeders

Why do birds come to feeders on some days and not on others? This question plagues many bird enthusiasts. The answer is multifaceted, driven by a complex interplay of environmental conditions and avian behavior. While a well-stocked feeder might seem like a constant invitation, birds don’t rely solely on them. Their decisions about visiting are influenced by a variety of factors, from the immediate weather to the broader seasonal changes.

Natural Food Availability

The abundance of natural food resources is a primary driver of feeder visitation rates. During periods of plenty, birds often ignore feeders altogether.

Seasonal Abundance: Spring and summer typically bring a bounty of insects, seeds, and berries. Birds will naturally prioritize these natural sources.
Weather Impacts: Favorable weather conditions during growing seasons can lead to an even greater surplus of natural food, further reducing feeder dependence.
Food Preferences: Different bird species have varying food preferences. A feeder stocked with sunflower seeds might be highly attractive to some birds, while others prefer insects or berries.

Weather Conditions

Weather plays a significant role in a bird’s decision to visit a feeder.

Extreme Cold: During periods of extreme cold, birds burn more energy to maintain their body temperature. Feeders become vital sources of high-energy food.
Snow and Ice: When snow and ice cover natural food sources, birds become more reliant on feeders. This is especially true for ground-feeding species.
Rain and Wind: Heavy rain and strong winds can make foraging difficult and energetically expensive, increasing the appeal of a sheltered feeder.

Time of Year/Seasonal Changes

Seasonal changes drastically alter the landscape and, consequently, bird behavior.

Breeding Season: During breeding season, many birds switch to a diet higher in protein (primarily insects) to feed their young. This reduces their dependence on seeds and grains.
Migration: Migratory birds may briefly increase their visits to feeders as they prepare for long journeys or refuel after arriving.
Post-Breeding Season: As young birds fledge and learn to forage independently, feeder activity can increase as these new individuals explore available food sources.

Predation Risk

The presence of predators can significantly influence feeder visitation.

Predator Sightings: The presence of hawks, cats, or other predators near a feeder can deter birds from visiting.
Feeder Placement: Feeders located in open areas with little cover can increase predation risk, making them less attractive to birds.
Feeder Design: Feeders that offer some protection from predators, such as those with cages or tunnels, may be more appealing.

Feeder Maintenance

The cleanliness and availability of food in a feeder are crucial factors.

Cleanliness: Dirty feeders can harbor bacteria and mold, making birds sick. Regular cleaning is essential.
Food Quality: Stale or moldy seeds are unappetizing and can be harmful. Always use fresh, high-quality birdseed.
Feeder Type: Different feeder types attract different species. Offering a variety of feeders can increase the diversity of birds visiting your yard.
Consistency: Keep the feeder stocked! Birds will quickly learn where to find reliable food sources.

Availability of Water

Water is just as important as food. Birds need water for drinking and bathing.

Water Source Near Feeder: Providing a bird bath or other water source near your feeder can attract more birds.
Winter Water: During freezing temperatures, providing a heated bird bath can be a lifeline for birds.

Weather	Extreme weather = Higher visitation, Mild weather = Lower visitation
Season	Breeding season = Lower visitation for some, Migration = Variable, Post-breeding = potentially Higher
Predation Risk	High predation risk = Lower visitation
Feeder Maintenance	Poor maintenance = Lower visitation, Good maintenance = Higher visitation
Water Availability	No water = Lower visitation, Water available = Higher visitation

Frequently Asked Questions about Bird Feeder Visitation

Why are birds visiting my feeder less often than they used to?

Several factors could contribute to decreased feeder visitation. The most common reason is the availability of natural food sources. As insects, berries, and seeds become abundant, birds naturally shift their focus away from feeders. Other possibilities include the presence of predators in the area, changes in weather patterns, or issues with the feeder itself (e.g., it may be dirty or the food may be stale).

What types of food attract the most birds to my feeder?

Black oil sunflower seeds are a favorite among a wide variety of bird species. Other popular options include nyjer (thistle) seed for finches, peanuts for woodpeckers and nuthatches, and suet for insect-eating birds. Offering a variety of foods will attract a greater diversity of birds.

Is it bad to feed birds year-round?

While some argue that feeding birds year-round makes them dependent on humans, research suggests that this is not generally the case. Birds are resourceful and will supplement their diet with natural food sources when available. Providing food year-round can be particularly beneficial during periods of extreme weather or when natural food is scarce.

How often should I clean my bird feeder?

Bird feeders should be cleaned at least once every two weeks, and more frequently during periods of heavy use or wet weather. Use warm, soapy water to scrub the feeder thoroughly, and then rinse it well and allow it to dry completely before refilling. You can also use a diluted bleach solution (1 part bleach to 9 parts water) to disinfect the feeder.

What are some signs that my bird feeder is causing problems for birds?

Signs that a bird feeder is causing problems include: a high number of sick or dead birds near the feeder, excessive seed waste around the feeder, and evidence of mold or bacteria growth on the feeder. If you notice any of these signs, stop feeding birds immediately and clean the feeder thoroughly.

Why do birds sometimes scatter seed on the ground around the feeder?

Birds may scatter seed for several reasons. Sometimes, they are simply being picky and selecting only their preferred seeds. Other times, they may be trying to cache seeds for later consumption. Some species are also messy eaters by nature.

How can I keep squirrels away from my bird feeder?

There are several strategies for keeping squirrels away from bird feeders, including using squirrel-resistant feeders, baffles, and placing feeders in locations that are difficult for squirrels to reach. You can also offer foods that squirrels don’t find appealing, such as safflower seeds. Keep in mind that squirrels are persistent, so it may take some experimentation to find a solution that works.

Should I be concerned about birds becoming dependent on my feeder?

While birds may become accustomed to visiting your feeder, they are not likely to become completely dependent on it. Birds retain their natural foraging instincts and will supplement their diet with natural food sources when available. Feeders should be seen as a supplementary source of food, not a complete replacement for natural food.

Why do different species of birds visit my feeder at different times of the day?

Some species, like chickadees and titmice, are early risers and may visit feeders first thing in the morning. Other species, like cardinals and finches, may be more active later in the day. This variation in activity patterns is often related to foraging strategies and predator avoidance.

What is the best way to provide water for birds?

A bird bath is an excellent way to provide water for birds. Choose a bird bath with a shallow basin and a rough surface to provide secure footing. Keep the bird bath clean and replace the water regularly. During freezing temperatures, use a heated bird bath to prevent the water from freezing.

How does the color of a bird feeder affect which birds will visit it?

The color of a bird feeder can subtly influence which birds are more likely to visit. Brightly colored feeders, like red and orange, can attract hummingbirds, while other birds aren’t particularly picky about feeder color. A more neutral color like green or brown is often a safe choice to attract a wide variety of birds.

Why do birds seem to disappear from my feeder when I am nearby?

Birds are naturally cautious and easily startled by movement. When you are near a feeder, they may perceive you as a potential threat and fly away. Try placing your feeder in a location that is visible from a window so you can observe the birds without disturbing them. Also, move slowly and avoid sudden movements when you are near the feeder. Understanding why do birds come to feeders on some days and not on others requires this nuanced understanding.
