Have you noticed a decline in goldfinches feeding on nyjer seed in your garden? There could be several reasons behind this change in behavior. One significant factor to consider is the recent weather patterns, especially if there has been a prolonged period of rain or high humidity.
Potential Mold Growth
When nyjer seed is exposed to excessive moisture, either from rain or condensation, it becomes susceptible to mold growth. Goldfinches may avoid eating moldy nyjer seed as it can be harmful to their health. If the seed at the bottom of the feeder has turned moldy, this could explain why the goldfinches are not consuming it.
Impact of Monsoon Season
During monsoon season or periods of heavy rainfall, the risk of mold development on nyjer seed increases significantly. The damp conditions create a breeding ground for mold spores, which can quickly spread to the bird feed. As a result, goldfinches may choose to avoid the contaminated seed, leading to a decrease in feeding activity.
Visibility of Mold
While mold may not always be visible to the naked eye, its distinct musty odor can deter goldfinches from consuming the nyjer seed. Even if the mold is not immediately noticeable, its presence can impact the taste and quality of the seed, causing the birds to seek alternative food sources.
Health Concerns for Birds
Goldfinches, like other bird species, are vulnerable to health issues resulting from mold exposure. Ingesting moldy seed can lead to digestive problems, respiratory issues, and weakened immune systems in birds. It is instinctual for goldfinches to avoid potentially contaminated food in order to safeguard their well-being.
Preference for Fresh Seed
Goldfinches are known for their discerning taste when it comes to selecting food. Fresh, high-quality nyjer seed is more appealing to these birds compared to older, moldy seed. If the feeder has not been refilled with fresh seed recently, the goldfinches may seek out other food sources until a replenishment is made.
Ensuring Seed Quality
To attract goldfinches back to your feeder, it is vital to prioritize the quality of the nyjer seed being offered. Regularly inspect the seed for any signs of mold or spoilage, and promptly replace it with fresh seed to entice the birds to return. By maintaining seed freshness, you can support the health and well-being of the goldfinches in your area.
Feeder Maintenance
Aside from monitoring the seed quality, proper feeder maintenance is essential for attracting goldfinches. Ensure that the feeder is clean, dry, and positioned in a sheltered area to prevent moisture buildup. Regularly clean the feeder to remove any mold or debris that could deter birds from feeding.
Weather Forecast Consideration
Before refilling the feeder with nyjer seed, check the weather forecast for any upcoming rain or high humidity conditions. It may be beneficial to wait for a dry spell before replenishing the seed to minimize the risk of mold growth. By aligning your feeding schedule with favorable weather patterns, you can enhance the feeding experience for goldfinches.
Alternative Feeding Options
If the goldfinches continue to avoid the nyjer seed due to mold issues, consider offering alternative food sources such as fresh fruits, mealworms, or sunflower seeds. Diversifying the feeder offerings can attract a wider variety of bird species while ensuring that the goldfinches receive the essential nutrients they need.
Observing Bird Behavior
Take the time to observe the behavior of goldfinches and other birds visiting your feeder. Note any changes in feeding patterns or preferences, as these observations can provide valuable insights into the factors influencing their food choices. By staying attentive to the needs of the birds, you can create a welcoming feeding environment that encourages frequent visits.
Conclusion
In conclusion, the reluctance of goldfinches to eat nyjer seed may be attributed to mold growth caused by recent weather conditions. By understanding the impact of weather on seed quality and bird health, you can take proactive steps to address these factors and attract goldfinches back to your feeder. Prioritize seed freshness, feeder maintenance, and weather considerations to create an inviting feeding space that supports the well-being of these beautiful birds.
