Many people enjoy feeding birds in their yards and neighbourhoods. However, as winter approaches each year, questions arise about whether it is safe and responsible to put out bird feeders. There are a few key factors to consider when deciding if and how to feed birds at this time of year.
Why do people feed birds?
People feed birds for a variety of reasons. Here are some of the main motivations:
– Enjoyment of watching birds up close
– Connecting with nature
– Helping birds survive challenging seasons
– Providing food and resources especially when natural sources may be scarce
– Learning about different bird species and behaviours
For many, seeing familiar birds visit their feeders provides comfort, entertainment, education, and a sense of giving back to nature. The beauty and activity birds bring into backyards and communities leads many people to want to support them.
When is it safe to feed birds?
While most experts agree that feeding birds undoubtedly helps them endure harsh weather and seasons, opinions differ on precisely when it is most beneficial or risky to do so. Here are some general guidelines on safe bird feeding times:
– Early fall before migration is considered safest, providing fuel for lengthy journeys.
– Winter is prime feeding season when food is scarce. Extra nutrition helps prevent starvation and maintain body warmth.
– Spring feeding is more controversial as natural food sources increase. It may discourage migration or promote dependency.
– Summer feeding is typically discouraged as it can interfere with natural foraging behaviours except for specially designed hummingbird feeders.
Many recommend year-round feeding in moderation so birds consistently have supplemental food without disrupting behaviours. Adjustments may be made depending on extreme weather events in a given area.
What are the risks of feeding birds?
While feeding birds is generally seen as helpful to them and enjoyable for people, there are some considerations regarding potential risks:
– Feeders can spread diseases between birds when they congregate. Regular cleaning and disinfecting is crucial.
– Feeding birds can make them dependent on human food sources instead of natural ones.
– Bears, raccoons, deer, and other wildlife may be attracted to bird feeders and cause issues. Proper feeder placement helps.
– Feeders with small seed slots may choke birds not adapted for it. Various feeder types are safer for different species.
– Moldy, rotten or contaminated food in feeders can make birds sick. Frequent monitoring, cleaning and replenishing food is important.
– Feeding inappropriate foods like bread, refined grains and sugary foods can be unhealthy for birds.
With proper care and management though, the consensus is that bird feeding does much more good than harm for bird populations. Just be sure to follow best practices.
Best practices for feeding birds
If you want to provide supplemental food for birds in your area while ensuring their health and safety, here are some tips:
Choose quality bird food
The right foods provide optimum nutrition for birds. Recommended options include:
– Black oil sunflower seeds
– Nyjer thistle seeds
– Safflower seeds
– Cracked corn
– Peanuts
– Suet cakes for insect-eating birds
Avoid cheap “filler” seeds like milo and wheat grains. Also do not offer junk foods like bread, chips, crackers or sugary products.
Use specialized bird feeders
Tailor feeders to the type of birds you want to attract:
– Platform feeders for multiple birds feeding on the ground
– Tube feeders for perching while eating ports
– Suet feeders for birds like woodpeckers to cling to while pecking
– Orioles like fruit halves skewed on spikes
– Hummingbirds drink nectar from specialized hummingbird feeders
Place feeders in optimal spots surrounded by bushes or trees so birds have refuge. Clean all feeders regularly with mild soap and water.
Prevent disease transmission
To stop feeders from spreading diseases:
– Clean feeders at least every two weeks with a 10% bleach solution
– Rake up debris, seed hulls and feces under feeders
– Separate different feeder types to reduce contamination
– Remove wet food and clean hummingbird feeders every few days
Promoting bird health is a top priority so take measures to mitigate disease risks.
Deter squirrels and other critters
To make sure bird food goes to birds:
– Use feeders with weight mechanisms limiting access to heavier animals
– Choose feeders with small ports or enclosed designs squirrels can’t invade
– Place feeders on poles away from trees, fences and wires that give access
– Apply capsaicin pepper solutions on feeders to deter squirrels (safe for birds)
– Install baffles above feeders to block access from above
– Bring feeders in overnight when not in use to reduce temptation
Be flexible and persistent to keep feeders “critter-proof”.
Monitor for problems
Check feeders frequently for:
– Evidence of “sick birds” like discharge, weakness or lethargy
– Build-up of wet, rotten or moldy food
– Pests like ants invading hummingbird feeders
– Issues like bee swarms, wasp nests or snakes around feeders
Discontinue feeding for two weeks if sick birds are observed. Then clean thoroughly before resuming use. Deal promptly with any other problems observed to keep birds safe.
Hazards birds face in winter
To understand whether feeding birds is warranted, it helps to know the specific hazards they encounter in the colder months:
Food scarcity
Many birds primarily eat insects, larvae, fruits or seeds. These foods become scarce in winter as bugs die off, fruit-bearing plants go dormant and snow covers seeds. Accessing enough calories is challenging.
Extreme cold
Frigid temperatures threaten birds’ survival. They require extra energy to maintain body heat. Small birds like chickadees lose 10% of body weight overnight in winter. Extra fat reserves help, but extreme cold stresses their limits.
Water sources freezing
Birds need to drink water daily, even in winter. Natural sources freeze over so finding liquid water gets extremely difficult. Dehydration becomes a real possibility.
Shelter inadequacy
Many birds nest and roost in tree cavities for shelter from the elements. But trees offer minimal insulation and protection in bitter winds, ice and heavy snow loads. Dangerous conditions force them to find refuge.
Predation risks
As natural food dwindles, predators like sharp-shinned hawks may increasingly target small bird flocks at feeding stations in winter for their own survival too. Vulnerable birds fall prey more easily.
With these combined threats, winter is the toughest stretch for birds. Supplemental feeding helps counteract some hazards when done properly.
Benefits of winter bird feeding
Offering extra food specifically helps birds endure winter’s challenges in a few key ways:
Boosts available calories
Feeders provide essential fats and energy when birds struggle to meet needs with natural food sources. This may make the difference in whether they maintain healthy body condition or not.
Prevents starvation
Extra fuel reduces likelihood of birds starving during extreme weather when their foraging is limited by deep snow, ice and high winds. Access to feeders helps prevent mass die-offs.
Supports stronger immune function
Adequate nutrition keeps birds’ immune systems stronger to help fight off viruses and illnesses during winter months. Poor diet leads to greater sickness.
Provides hydration
Heated bird baths and drippers give vital water sources when natural ones freeze over. Dehydration is a real threat otherwise.
Offers shelter options
Feeders placed near brush piles, roost boxes and dense bushes provide escape options from the elements that trees don’t offer alone.
Winter feeding is overall crucial to help supplement birds’ survival needs during the harshest conditions of the year when their mortality risks are greatest.
Best winter feeding practices
Follow these tips to maximize benefits for wintering birds visiting your feeders:
Offer high calorie foods
Prioritize energy-dense options like black oil sunflower seeds, suet, peanuts and nut butter suet cakes. Avoid filler grains like milo or corn.
Provide both seeds and suet
Seeds offer carbohydrates while suet provides fat. Combining these macronutrients gives balanced nutrition.
Use insulating feeder materials
Choose feeders made of vinyl, plastic or wood which don’t conduct heat away versus metal materials.
Place feeders out of the wind
Situate feeders in protected spots near trees, fences or bushes to provide cover from strong winds.
Clear snow around feeders
Remove accumulations of snow beneath feeders so birds have access. Set feeders on elevated stands above snow line.
Offer fresh water
Provide heated bird baths with trickle drippers, immersion heaters or solar power to prevent freezing.
Clean feeders regularly
Disinfect feeders at least monthly to prevent disease transmission when birds congregate.
Limit food waste
Only put out small amounts birds will finish daily to reduce chances of spoilage in wet weather.
A few simple strategies go a long way towards making feeders safe, nutritious and welcoming for birds facing winter’s harshness.
Tips for safe summer bird feeding
While winter feeding is vital, many people enjoy feeding birds year-round. Here are tips for safe summer feeding:
Offer bird-healthy foods
Stick to quality seeds, nuts and fruits. Avoid cheap grains and human junk food which lacks nutrients birds need while breeding.
Clean feeders weekly
Prevent disease transmission when birds crowd feeders. Hot summer temperatures promote bacteria growth.
Place feeders in shady spots
Keep feeders out of direct sun to stop food spoilage and fermentation which can sicken birds.
Avoid feeding birds on ground
Platform feeders foster disease spread through droppings accumulation. Elevated feeders are safer.
Remove water features
Birdbaths and drippers can breed mosquitoes carrying diseases. Limit water access except for hummingbird feeders.
Use mesh covers
Loosely drape feeders with mesh bags to reduce crowding while allowing entry.
Eliminate food waste
Sweep up fallen seeds, hulls and stale food to prevent contamination. Birds forage naturally in summer.
Monitor for issues
Watch for signs of sick birds, harbourage by predators like hawks and food spoilage indicating overfeeding.
With a few precautions, you can supplement birds’ diets in summer without creating dependency.
Transitioning feeding from winter to spring
As winter transitions to spring, you’ll want to gradually taper birds off feeders and redirect them to seek natural food again:
Reduce feeder offerings
Slowly cut back on amounts of seed, suet and nuts you put out daily over a few weeks. Avoid abrupt stoppage.
Discontinue tray feeders
First eliminate platform and tray feeders birds reach easily first to reduce dependency. Then remove hanging feeders.
Allow natural food to increase
As bugs emerge and native plants bloom again, birds will decrease reliance on feeders as options diversify.
Remove feeders entirely
Take down feeders completely later in spring once birds show decreased usage and return to normal foraging.
Clean and store feeders
Once removed, thoroughly disinfect feeders before storing them away safely until winter returns.
With some care, you can smoothly transition birds back to their natural food sources as spring and summer return.
Impact of bird feeding on migration
One concern people have is whether feeding birds hinders their migration in spring. Here is some perspective on this issue:
How migration works
Bird migration is prompted by seasonal cues like changes in day length, temperatures, and food availability. These triggers happen even if feeders are available.
Feeders don’t prevent migration
Research shows the majority of birds still migrate normally even if ample feeder food remains. Their instincts take over despite easy feeder access.
Some delays in migration happen
However, very small percentages of certain species like Black-capped Chickadees and Downy Woodpeckers may delay migration by a few days when feeders remain available. These represent very minimal numbers though.
Discontinuing feeding reduces impacts
This is why experts recommend gradually reducing supplemental feeding as natural food returns in spring. This limits any disruption to migration patterns.
Migration is driven by multiple factors
Photoperiods, temperatures, genetics and food are all complex drivers of migration. Feeders don’t override all those elements combined.
So supplemental feeding appears to have negligible impacts on bird migration overall. Responsibly tapering feeders in spring prevents any minor delays. Enjoy feeding birds according to seasons.
Differences between winter and summer feeding
Bird feeding does differ significantly between winter and summer in a few key ways:
Factor | Winter Feeding | Summer Feeding |
---|---|---|
Purpose | Provide supplemental nutrition and energy when natural food is scarce | Offer extra food as minor supplement since natural food is abundant |
Foods | High fat/calorie like suet, nuts and sunflower seeds | Standard seeds, fruit and nectar; Avoid high fat foods |
Frequency | Daily feeding recommended | Limited, intermittent feeding recommended |
Feeder Cleaning | Every 2-4 weeks | Weekly |
Disease Risks | Lower due to cold temperatures | Higher due to heat and humidity |
Feeder Placement | Protected sites near cover | Shady locations away from sun |
Water Provision | Heated bird baths | Avoid open water sources; use nectar feeders only |
Tailoring feeding practices to winter versus summer makes the efforts more responsible, safe and beneficial for birds.
Risks to birds stopping feeding abruptly
After relying on backyard feeders for winter nutrition, birds can face risks if feeders are removed too quickly or abruptly:
Nutritional deficits
An immediate halt while natural food is still scarce means reduced calories when birds need them most ahead of spring breeding.
Starvation risk
Birds may starve without transition time for their foraging skills to adjust, especially after generations grew dependent on feeders.
Stress and shock
A sudden loss of expected food sources can disorient birds and disrupt advantageous feeding patterns.
Increased competition
More competition at remaining feeders may occur if some are removed rapidly, impacting certain species.
Damage to social structure
Flock numbers, dynamics and territory claims around feeders could be thrown off by sudden withdrawals.
Delayed migration
Some birds may delay migration looking for expected feeders rather than transitioning to seeking natural food.
With a responsible gradual transition, risks are minimized. But an abrupt halt to feeding can certainly be detrimental to the birds.
Conclusion
Feeding birds supplementary food, especially in winter, provides crucial support when their survival is challenged by harsh conditions. But implementing best practices makes the activity most beneficial. Follow guidelines on quality foods, proper feeder protocol, cleaning routines and seasonal adjustments. With conscientious effort, bird feeding can certainly be a safe, healthy and enjoyable activity for birds and people alike. Be knowledgeable, be responsible and enjoy the rewards of closer bird connections in your backyard.
