Grackles are fascinating birds with intriguing behaviors and striking appearances. There are 10 living species of grackle in the world, along with one known extinct species. There are three Birdorable grackle species (read on to learn which ones we feature!). These New World birds live in various habitats across North and South America. Here are some interesting facts about these lively and adaptable birds!

Social Structure

Grackles are highly social birds, often forming large flocks that can number in the thousands. These flocks can create quite a spectacle, especially during roosting or migration periods.

Unique Vocalizations

Grackles have a wide range of vocalizations, including whistles, croaks, and clicks. They are known for their loud, harsh calls, which can often be heard in urban areas.  Calls of the Common Grackle have been compared to the noise made by rusty gate hinges. These varied vocalizations help them communicate within their social groups, attract mates, and signal danger. Additionally, grackles can mimic other birds and environmental noises.

Dietary Flexibility

Grackles are omnivorous and highly opportunistic feeders. Their diet includes insects, small mammals, eggs, seeds, fruits, and even human food scraps. They are known to forage in fields, lawns, and dumpsters alike.

Iridescent Feathers

Grackles are known for their glossy, iridescent feathers that can shimmer in shades of blue, purple, green, and bronze, especially in sunlight. This iridescence is visible due to the microscopic structure of their feathers that affect the way light appears when the bird moves.

Bold and Aggressive Behavior

Known for their boldness, grackles often exhibit aggressive behavior towards other birds and even larger animals. They can be seen chasing away other birds from feeders or scavenging spots. When attacking other birds, they will peck, bite, and scratch.

Interesting Courtship Displays

During courtship, male grackles perform elaborate displays to attract females. These displays often include fluffing their feathers, spreading their wings and tail, and making a variety of calls. Male Great-tailed Grackles will fluff out their feathers, fan out their tails, and quiver their wings in order to attract females.

Sexual Dimorphism

There is noticeable sexual dimorphism in grackles. Males are generally larger and more iridescent than females. This difference is particularly evident in species like the Boat-tailed Grackle, where females differ in both size and plumage (they are mostly brown).

Pest Control Benefits

By feeding on insects, grackles help control pest populations. They consume a significant number of agricultural pests, which can be beneficial for farmers. Unfortunately, several grackle species are also seen as agricultural pests, with large flocks happily consuming crops like corn.

Adaptability to Urban Environments

Grackles have successfully adapted to urban environments, thriving in cities and towns where they find ample food and nesting sites. Their ability to live in close proximity to humans has contributed to their widespread presence.

Species Diversity

There are several species of grackles, including the Common Grackle, Great-tailed Grackle, and Boat-tailed Grackle, each with unique characteristics and habitats. The seven other living species of grackle are: Nicaraguan Grackle; Greater Antillean Grackle; Carib Grackle; Red-bellied Grackle; Velvet-fronted Grackle; Golden-tufted Grackle; and Colombian Mountain Grackle. The Slender-billed Grackle became extinct around 1910.

Grackles are Great

From their stunning iridescent feathers to their interesting courtship techniques, grackles belong to an interesting family of New World birds. From familiar backyard birds to elusive tropical species, grackles remind us of the intricate balance within ecosystems and the importance of each species in maintaining ecological harmony. 

Birdorable Grackle Gifts

Did you catch the three grackle species we have here at Birdorable? They are they Common Grackle, the Boat-tailed Grackle, and the Great-tailed Grackle! Here are some apparel and gift options featuring our Birdorable grackles. 

Two of our newest birds here at Birdorable are the Brown Tanager and Brown-flanked Tanager. The two different species may seem similar at first glance due to their names, but they have distinct characteristics, ranges, habits, and habitats. Let's dive into the details of these two fascinating birds.

The Brown Tanager

The Brown Tanager (Orchesticus abeillei) is a small bird endemic to Brazil where it is found in the highlands of the southeast.  It prefers the dense, humid forests of the Atlantic Forest biome, often at elevations between 900 and 2,000 meters. This bird's plumage is predominantly brown, as its name suggests, but it can have subtle variations in shade. The Brown Tanager is relatively elusive, making it a treat for birdwatchers who manage to spot it.

The diet of the Brown Tanager consists mainly of insects; fruits are an occasional treat. Brown Tanagers are often seen foraging alone or in pairs, though they may join mixed-species feeding flocks during certain times of the year.

The Brown Tanager is the only species in its genus, Orchesticus. 

The Brown-flanked Tanager

The Brown-flanked Tanager (Thlypopsis pectoralis) is also an endemic species, this one found only in Peru.  This bird favors montane forests, typically between 2,500 and 3,200 meters in elevation. The Brown-flanked Tanager is easily recognizable by its distinctive rufous-orange head and breast on an otherwise drab grey-brown body.

The Brown-flanked Tanager's diet is comprised mostly of prey items including insects, moths, and caterpillars. One interesting aspect of the Brown-flanked Tanager's behavior is its participation in mixed-species flocks. These flocks, common in Andean forests, consist of various bird species that move together while foraging. This behavior helps reduce the risk of predation and increases foraging efficiency.

The Brown-flanked Tanager is a member of the genus Thlypopsis, a group of 8 tanager species with a widespread range across parts of South America.

A Tale of Two Tanagers

For bird enthusiasts, observing these two species offers a chance to appreciate the diversity of tanagers and the unique adaptations that allow them to thrive in their respective environments. Whether it's the quiet beauty of the Brown Tanager in Brazil's highland forests or the active presence of the Brown-flanked Tanager in the Andean montane forests of Peru, each bird brings its own charm to the avian world. We proudly welcome these tropical avian friends to our big Birdorable family!

Father's Day is a special occasion to honor the dedication, love, and hard work of fathers and father figures across the globe. While we celebrate the human dads in our lives, it's also a perfect time to recognize the incredible fathers in the animal kingdom, particularly among birds. Bird dads come in all shapes and sizes, each with unique and fascinating parenting roles that highlight their dedication to nurturing and protecting their offspring.

Father's Day will be celebrated on June 16, 2024. That's just 10 days away -- which means you still have time to find something for your pop. If dad likes birds, be sure to check out our Birdorable Amazon shop, where items ship fast and free with Amazon Prime. 

Back in 2019, we shared some fun facts to mark the day: Fun Avian Dad Facts for Father's Day. As dad's day approaches this year, let's take a look at some more awesome facts about avian dads.

Father rheas are dedicated single dads. After constructing the nest alone, they court multiple females, who together may lay up to 60 eggs in his nest. The male incubates the eggs and raises the chicks on his own. He protects and cares for the young until they are old enough to fend for themselves​ -- at least six months.

Father Killdeer are very active in the nesting process. They participate in nest building, typically initiating the creation of the scrape. They incubate the eggs, and do most of the overnight shift. They also help to protect the nest and chicks by performing the well-known Killdeer injury-feigning display. 

Red-winged Blackbird dads are known for their territorial nature, especially during the breeding season. They arrive first on breeding sites and establish territory. They will fiercely defend their nesting area throughout courtship, nest-building, and chick-rearing. Part of this defense includes a predator alert system involving different call types for different threats. Though the females build the nests, males participate in "Symbolic Nest-building Display" which involves play-nest-building.

Common Loon dads are active participants in both nest-building and chick-rearing. They typically choose the nesting site and work together with the female to build the nest. They share in egg incubation, and both carry chicks on their backs to keep them warm and safe, and teach them to dive and catch fish.

Male sandgrouse in arid regions are known for their unique method of providing water to their chicks. They soak their belly feathers in water and fly long distances back to the nest, allowing the chicks to drink from their feathers. 

Father Great Horned Owls are excellent providers. When their chicks are young, the males do all of the hunting and bring food to the female and the chicks, ensuring that the family is well-fed. They also help protect the nest from potential threats.

Periodical cicadas are among nature's most fascinating insects, with their synchronized emergences occurring every 13 or 17 years. These insects spend most of their lives underground as nymphs, feeding on tree roots. When they finally emerge, they transform the landscape in remarkable ways, not just for themselves, but also for the local bird populations and broader ecosystems.

In many locations across the midwest and southeast of the United States, the emergence of two broods of cicadas are approaching their peak. Brood XIII (the Northern Illinois Brood, a 17-year cicada) and Brood XIX (the Great Southern Brood, a 12-year cicada) are both emerging right around now. Do you have cicadas where you live? Is this the first time you've experienced this phenomenon?

For birds, this sudden appearance of millions of cicadas provides a significant and timely food source, particularly beneficial during the breeding season.

The life cycle of periodical cicadas is both unique and complex. Cicadas spend 13 or 17 years underground as nymphs, feeding on the sap from tree roots. When they finally emerge, usually overnight, in late spring, they come out in such vast numbers that their presence can’t be ignored. They climb onto nearby vegetation or other surfaces including fences and buildings, where they molt one last time to become winged adults. The sight and sound of millions of cicadas filling the air can be overwhelming, but for birds, it’s an ecological feast.

For local birds, this mass emergence is like a buffet laid out for them. Birds such as American Robins, Blue Jays, and Northern Cardinals feast on the cicadas, taking advantage of the sudden abundance of food. This feeding frenzy can have several impacts on bird populations.

It provides a significant nutritional boost. The abundance of cicadas offers an easy and nutritious food source, which is particularly advantageous during the breeding season when birds need extra energy to care for their young. The high protein content of cicadas helps adult birds maintain their strength and improves the health and growth rate of their chicks.

The abundance of cicadas can influence bird behavior and breeding success. Some studies suggest that bird species with access to periodical cicadas may produce more offspring during emergence years. This is because the high protein content of cicadas helps improve the health and vitality of both adult birds and their young. This increased food availability can lead to more successful broods, thereby potentially boosting local bird populations in the years following a cicada emergence.

With cicadas providing a plentiful food source, predation pressure on other insects and small animals may decrease, allowing these populations to thrive as well. With birds focusing on the abundant cicadas, other prey species might experience a temporary reprieve, which can impact the broader ecosystem. This shift in predation and its potential impacts can illustrate the interconnection of these ecological events.

The impact of cicada emergences isn't limited to immediate bird populations. The sudden influx of nutrients into the ecosystem can have cascading effects. When birds eat cicadas, they also help distribute nutrients through their droppings. These nutrients can enrich the soil, promoting plant growth and benefiting the entire ecosystem. The decaying bodies of cicadas that are not eaten contribute to soil fertility, fostering a healthier environment for various plant species.

There are also potential drawbacks. The sudden surge in cicada numbers can lead to temporary imbalances. For instance, some birds might become so focused on cicadas that they neglect other food sources, which could affect their diet diversity in the short term. Additionally, the noise created by millions of male cicadas singing to attract mates can be overwhelming, although it subsides after a few weeks. The maximum lifespan of adult cicadas is just one month.

Understanding the role of periodical cicadas in ecosystems underscores the intricate connections between species. These insects, which might seem inconsequential or even annoying to some, play a vital part in maintaining ecological balance. Their predictable emergences offer a unique opportunity to observe natural processes and the interdependence of life forms.

For birdwatchers and nature enthusiasts, cicada years present a chance to witness extraordinary interactions. Watching birds capitalize on this bonanza is a reminder of the adaptive strategies wildlife employs to survive and thrive. It’s a perfect living example of the resilience and complexity of nature, where even the most unusual life cycles have their place and purpose.

The emergence of periodical cicadas is a natural marvel with significant ecological implications. These events provide crucial food resources for birds, influence breeding success, and contribute to nutrient cycling in ecosystems. By appreciating these interactions, we gain deeper insights into the delicate balance of our natural world.
