Two dairies can sit right next to each other. They may have similar herd sizes, use comparable feed rations, and operate in nearly identical environments.
Yet one facility has starlings covering the feed bunks, gathering around commodity bays, and moving through the mixing area. The other has relatively few birds.
What makes the difference?
Sometimes, the answer has less to do with the dairy itself and more to do with how easily birds can access its feed.
For agricultural distributors working with dairy farms, feedlots, and other livestock operations, this creates an important opportunity. By learning to recognize open-feed situations, you can identify potential bird-control problems before they become major issues for your customers.
European starlings are opportunistic feeders. They take advantage of readily available food sources, and livestock operations can provide exactly what they need.
Grain, corn, protein supplements, and other components of livestock rations can attract starlings when those materials are exposed and accessible.
Unlike wildlife that must search for food across a large area, starlings at a livestock facility may find a dependable food source concentrated in one location.
That can make a dairy or feedlot an attractive place to return to day after day.
When birds find an accessible food source, they may continue using it as long as the conditions remain favorable. Other factors, including nearby water, suitable roosting areas, shelter, and the presence of established flocks, can also influence where birds congregate.
This helps explain why two neighboring dairies can experience very different levels of bird activity.
One facility may have feed exposed in several locations, while the other has fewer opportunities for birds to access the ration.
The first step in identifying a potential bird problem is to look at the facility from a bird's perspective.
Where would a bird land? Where could it feed? And how easy would it be to return tomorrow?
When walking a dairy or livestock account, don't focus exclusively on the feed bunk or the location where birds are most visible.
Instead, follow the entire path that feed takes from delivery to consumption.
Birds may be exploiting opportunities in places that aren't immediately obvious to the customer.
Feed bunks can provide a convenient feeding opportunity when ration is exposed and birds can reach it.
Starlings may gather along the bunk, land on accessible surfaces, and feed on exposed ration. Depending on the size of the flock and the amount of feed available, repeated visits can create ongoing contamination and feed-loss concerns.
Look for birds feeding directly from the ration, droppings accumulating around feeding areas, and repeated bird activity during feeding periods.
Ask the customer whether birds are present throughout the day or whether activity increases at particular times.
That information can help establish when and where the problem is occurring.
Commodity bays are another important place to inspect.
Depending on how a facility is designed and operated, these areas may contain corn, grain, silage, or other feed ingredients that are accessible to wildlife.
Even when most feed is stored appropriately, exposed material can create an attractive feeding opportunity.
Look for uncovered commodities, spilled material around bay edges, and feed that remains accessible between handling activities.
Also consider what happens during loading, unloading, and material transfers. A facility may have relatively secure storage but still expose feed during routine operations.
The goal is not simply to identify where feed is stored. It is to understand where birds can access it.
The mixing area deserves particular attention because feed is being handled, transferred, and prepared for delivery to livestock.
Spilled ingredients, residual feed, and material left around equipment can provide additional opportunities for birds.
Ask the customer what happens after a mixing cycle. Is spilled feed cleaned up promptly? Are transfer areas kept clear? Does exposed material remain on the ground or on accessible equipment?
Small amounts of feed may seem insignificant when viewed individually. However, repeated spills and consistent access can make an area worth investigating.
A good site assessment considers both the main feed supply and the smaller opportunities that occur during daily operations.
Don't stop your inspection at the storage area.
Follow the route from the delivery truck to the storage bay, from storage to the mixer, and from the mixer to the animal.
Each transfer point can reveal a different opportunity for birds to access feed.
Consider whether feed is exposed during unloading, whether material spills along travel routes, and whether birds can reach feed while equipment is waiting or being cleaned.
These details help distributors have more useful conversations with customers because they connect bird activity to the actual operation of the facility.
Once you've inspected the facility, ask the customer a simple question:
"Is your feed open to the sky anywhere between the truck and the animal?"
This question encourages the customer to think about the entire feeding process rather than focusing only on the birds they see.
They may immediately identify an uncovered commodity bay, an exposed mixing area, or a feed bunk where starlings gather regularly.
They may also realize that they have never evaluated their feeding operation from a bird's perspective.
That opens the door to a more productive discussion.
Instead of starting with a product or a treatment recommendation, you're starting with the conditions that may be attracting the birds.
Follow up with a few practical questions:
These questions help build a clearer picture of the problem and identify areas that may need a closer assessment.
Bird activity around livestock operations is not just a nuisance. Large numbers of starlings can create several operational concerns.
Feed is one of the largest operating expenses for many livestock producers. When birds consume feed intended for cattle or other livestock, that represents a potential loss of a resource the producer has already paid for.
The impact depends on factors such as flock size, the amount of feed available, how long birds remain at the facility, and the proportion of their diet obtained there.
Spilled feed and contamination may create additional waste.
The amount lost at any individual facility can vary considerably, so avoid assuming a fixed dollar figure without assessing the specific operation. The important question is whether the birds are consuming enough feed to create a meaningful financial concern.
Starlings can leave droppings on and around feed-handling surfaces, storage areas, equipment, and other parts of the operation.
Bird droppings can contain microorganisms, and contamination can create food-safety and animal-health concerns depending on the organism, the exposure route, and the conditions involved.
The presence of birds does not automatically mean that a particular disease has been transmitted. However, repeated bird activity around feed and livestock environments is a legitimate reason to evaluate sanitation and biosecurity practices.
Distributors can help customers recognize that bird pressure is not only about what birds eat. It is also about where they feed, where they travel, and what they contaminate along the way.
A reliable food source can help keep birds returning to the same location.
If a dairy provides accessible feed day after day, birds may continue using the facility even after the customer removes a few birds or cleans up visible droppings.
This is why identifying the conditions that support bird activity matters.
Removing birds without evaluating the food source, roosting opportunities, and other attractants may leave the underlying problem unchanged.
Effective bird management starts with understanding why birds are using the property in the first place.
Returning to our original question: why can one dairy have birds everywhere while the next facility has relatively few?
The answer may involve several differences.
One dairy may have more exposed feed. Another may clean up spills more consistently. One may have convenient roosting structures nearby, while the other offers fewer suitable places to settle. Differences in water access, facility layout, surrounding land, and flock behavior can also affect bird activity.
Feed accessibility is not the only factor, but it is one of the most practical starting points for an inspection.
For agricultural distributors, this distinction matters because it creates a repeatable way to identify potential opportunities across a territory.
You do not need to wait for a customer to complain about a major starling problem. You can start by recognizing the conditions that may attract birds and asking questions about what is happening on-site.
Once you identify accessible feed and signs of bird activity, the next step is to determine the scope of the problem.
Start by documenting where birds are feeding, how frequently they appear, and which parts of the operation are affected.
Then consider the available management options.
Where practical, improving feed storage, cleaning up spills, and reducing unnecessary access to exposed feed can help address attractants. These measures should be considered alongside other appropriate bird-management strategies.
Not every facility can eliminate exposed feed entirely. Livestock operations must move large quantities of material efficiently, and some feeding systems naturally involve open areas.
When access cannot reasonably be eliminated, a broader bird-control plan may be necessary.
That plan should account for the species involved, bird behavior, the layout of the facility, applicable regulations, site-specific restrictions, and the customer's operational requirements. Depending on the situation, professional bird management may complement sanitation, exclusion where feasible, and other appropriate control measures.
The objective is to address the conditions contributing to the problem rather than treating visible bird activity as an isolated issue.
For distributors, this is also an opportunity to bring additional value to the customer conversation. You're helping the producer identify a problem, understand its potential consequences, and determine what should happen next.
Take this approach into your territory.
Build a list of 10 dairy or livestock accounts with open-feed situations. Focus on facilities where feed is exposed in commodity bays, mixing areas, feed bunks, or other locations between delivery and consumption.
For each account, try to identify:
You don't need to have every answer before adding an account to your list. The goal is to identify promising opportunities that deserve further investigation.
Send your list to Lloyd or Solomon. They can help you prioritize the accounts and determine which ones may warrant a more detailed bird-control assessment.
The more you practice looking at a facility from a bird's perspective, the easier it becomes to recognize potential problems before the customer knows how to describe them.
Birds don't choose a livestock facility at random. Food availability, water, shelter, roosting opportunities, and other environmental conditions can all influence where they gather.
When you see a dairy with recurring starling activity, start by following the feed.
Look at the bunks. Inspect the commodity bays. Walk through the mixing area. Follow the route from delivery to the animal.
Then ask the question that can open the conversation:
"Is your feed open to the sky anywhere between the truck and the animal?"
You may discover the reason birds keep returning, a problem the customer hasn't fully recognized, and an opportunity to help them develop a better bird-management strategy.
Open feed is an open invitation.
