Icteridae
The Baltimore Oriole demonstrates remarkable agility, particularly whilst foraging. Their ability to hang upside down from branches and perform acrobatic manoeuvres to reach food showcases their exceptional manoeuvrability. Their lightweight frame and precise movements make them particularly adept at navigating through foliage.
Whilst not exceptionally strong, Common Grackles possess moderate strength for their size. Their ability to crack open acorns and manipulate various food items indicates a respectable level of physical prowess, though they're not among the strongest birds in their size category.
Common Grackles exhibit remarkable adaptability. Their diverse diet, ability to thrive in various habitats from woodlands to urban areas, and their clever use of tools for foraging demonstrate exceptional adaptiveness. Their success in human-modified landscapes further underscores this trait.
These birds show a moderate to high level of aggressiveness, particularly in defending their nests and competing for resources. Their willingness to prey on other birds' eggs and nestlings, as well as their dominant behaviour in mixed flocks, indicates a notable aggressive streak.
Outstanding endurance demonstrated by their extraordinary 12,500-mile annual migration journey, one of the longest among North American songbirds. Their ability to maintain hovering flight displays and traverse vast distances across multiple continents showcases remarkable stamina.
