9 Main Differences
Spotting the difference between the Red Shouldered Blackbird vs Red-Winged Blackbird can feel like playing birdwatcher detective! I remember standing in a marsh, binoculars up, confused at first glance. But once you know these key traits, it’s easier than you think.
1. Size and Weight
The Red-Winged Blackbird is bigger. Males measure about 8.7–9.4 in (22–24 cm) and weigh around 2.3 oz (65 g). The Red Shouldered Blackbird stays smaller at 7.5–8.3 in (19–21 cm) and weighs about 1.8 oz (50 g). Quick tip: If the bird looks small for a blackbird, it might be the Cuban native!
2. Range and Distribution
Here’s a fun fact: Red-Winged Blackbirds spread across most of North America. Red Shouldered Blackbirds live only in Cuba. So if you’re birding in the U.S. or Canada, you’re almost always seeing a Red-Winged.
3. Habitat Preference
Red-Winged Blackbirds love marshes, fields, and wetlands. Red Shouldered Blackbirds stick to Cuban lowland swamps. Location alone often solves the ID puzzle.
4. Flight and Escape Behavior
Both fly fast with undulating patterns. But I’ve noticed Red-Winged Blackbirds show off their red and yellow shoulder flashes more during flight.
5. Feeding Habits
Both enjoy seeds and insects. However, Red-Winged Blackbirds often raid crop fields, while Red Shouldered Blackbirds stick to natural Cuban wetlands.
6. Breeding and Nesting
Red-Winged Blackbirds build nests in tall cattails or shrubs. The Red Shouldered Blackbird also nests low but only in Cuba’s marshes.
7. Hunting Techniques
Both forage on the ground and in shallow water. Their style is more “grab and go” than stealth.
8. Personality and Interaction
I’ve had Red-Winged Blackbirds dive-bomb me near their nests! They’re bold. Red Shouldered Blackbirds are shyer, likely due to fewer human interactions.
9. Conservation and Status
Red-Winged Blackbirds are common, even called abundant. Red Shouldered Blackbirds are rarer and more vulnerable, with limited range and smaller numbers.
Red-shouldered Blackbird
The red-shouldered blackbird is a lesser-known gem, found only in the swamps of Cuba. It’s not just beautiful—it’s full of personality and uniqueness that set it apart from its more common cousin, the red-winged blackbird.

- They sing in pairs. I’ve heard male and female birds duet—it’s soft, sweet, and rare in blackbirds.

I still remember the day that sparked my love for birds. I was just a kid, sitting in my backyard, when a tiny bird landed near me. It moved so fast, its feathers flashing in the sunlight, and then it sang—soft, clear, and almost magical. In that moment, birds became more than just creatures in the sky. They became a mystery I wanted to solve.
That curiosity never faded. It led me to study Biology at the University of Scranton, where I dove deep into the science of birds—their behavior, their calls, and the incredible ways they survive. Today, that same passion drives me, and through Earth of Birds, I get to share it with you.
