May is when spring stops feeling frantic and starts feeling lush. Everything that was rushing to leaf out and bloom in April is now settled into growing. The chaos calms down a bit. Not completely, but enough that you can breathe and actually enjoy things instead of frantically chasing changes.
This is probably my favourite nature month. The weather is usually gorgeous. Everything is green and alive. Birds are singing constantly. Flowers are everywhere, but not overwhelming. It’s like nature found its groove and is just vibing. That sounds silly, but it’s accurate.
May also have this perfect light. The sun is higher but not oppressive. Mornings are bright and fresh. Evenings last forever. You can be outside comfortably for hours. This makes nature watching easy and pleasant, rather than a battle against the weather.
I find myself spending way more time outside in May than in any other month. Not because I’m trying to document things, though I still do that. Just because it feels good. Being outside in May is restorative in ways that are hard to explain. You just feel better.
Here’s what catches my attention this month. May has its own rhythm and characters. Some things from April continue. New things begin. It’s a transition from spring’s explosive start into summer’s steady growth. Pay attention to both.

Late Migrant Birds Arrive
Most migrants already arrived in March and April. But some species wait until May. These late arrivals include flycatchers, vireos, and some warbler species. Waiting makes sense because they need abundant insects. May provides that.
Flycatchers are fun to watch. They sit on exposed perches and dart out to catch flying insects. Eastern phoebes, least flycatchers, and great crested flycatchers all arrive now. Their hunting technique is distinctive. Once you learn it, you’ll spot flycatchers easily.
Vireos skulk in the tree canopy, singing persistently. Red-eyed vireos sing seemingly endless phrases. They sound like they’re asking and answering questions. Warbling vireos have beautiful, flowing songs. These birds are easier to hear than see.
The Baltimore Orioles are fully settled now. Males sing from treetops and defend territories. Indigo buntings arrive and perch on powerlines singing. Rose-breasted grosbeaks visit feeders. These colourful birds make May special.
In Europe, late migrants like spotted flycatchers return. Swifts scream overhead in urban areas. Australia’s autumn brings different patterns as birds respond to changing seasons. Check eBird for recent sightings. Join local bird walks to learn songs and identification tips.
Migration isn’t over. Keep watching and listening.

Nesting Activity Peaks
May is prime nesting time for most songbirds. Some early nesters already have fledglings. Others are just starting. A few species will nest multiple times. Walk through any habitat, and you’ll see birds carrying food to hidden nests constantly.
Robins might be on their second clutch. First babies fledged in April. Now parents start over with new eggs. This happens while they’re still feeding first-brood fledglings. Parent robins are busy. Watch them hunting worms while young from the previous nest beg nearby.
Warblers that just arrived are establishing territories and courting. Ovenbirds build dome-shaped nests on forest floors. Common yellowthroats nest in marshy vegetation. Each species has specific requirements. Providing diverse habitats supports more nesting birds.
Cavity nesters like tree swallows and bluebirds are feeding nestlings. If you have nest boxes, the babies are growing rapidly now. Resist checking too often. Once a week, maximum. Parents need to focus on feeding without being disturbed by humans.
Hawks and owls have large nestlings. Baby red-tailed hawks are visible in stick nests. Great horned owl fledglings perch near nests. These young raptors are fluffy and awkward. They can’t fly well ye,t but they’re huge. The Cornell Lab NestWatch program needs observations from backyard birders.
Nesting season is a peak stress time for birds.

Garden Plants Bloom Heavily
May gardens explode with colour. This is when most ornamental plants hit their peak. Lilacs, azaleas, rhododendrons, and tulips create displays. Even if you’re not into gardening, neighbourhood walks become beautiful this month.
Lilacs smell amazing and attract pollinators heavily. Their fragrance carries on warm evenings. Different varieties bloom at slightly different times. Purple is classic, but whites, pinks, and deep burgundies exist, too.
Azaleas and rhododendrons bloom in shades of pink, red, white, and purple. Some are native, many are ornamental. The massive blooms are impressive. Bumblebees work them constantly. These shrubs become pollinator hotspots.
Iris, peonies, and early roses begin blooming. Bleeding hearts dangle their heart-shaped flowers. Columbines have intricate blooms that hummingbirds love. Even common plants like hostas send up flower spikes.
Native plants bloom, too. Wild geraniums create pink carpets in woodlands. Spiderwort has three-petaled purple flowers. Phlox adds colour to meadows. These natives often support more insect species than ornamentals. The Lady Bird Johnson Wildflower Center promotes native planting.
Walk slowly and notice what’s blooming. Even weeds have flowers worth examining.

Turtles Lay Eggs
May through June is when most turtles lay eggs. Females leave water or woodland to find sunny spots with sandy or loose soil. They dig holes with their back feet and deposit eggs. This makes turtles vulnerable because they’re travelling across roads and through yards.
Watch for turtles crossing roads in late afternoon and evening. Females travel surprisingly far to find ideal nesting sites. If you see one, help her across in the direction she was heading. Don’t relocate her or turn her around. She knows where she’s going.
Box turtles dig nests in fields and forest edges. Painted turtles nest near water but often cross roads to reach better sites. Snapping turtles are legendary for travelling long distances. A huge snapping turtle in your driveway might be a nesting female.
After laying, females cover the nest and leave. They provide no parental care. Eggs incubate through summer and hatch in late summer or fall. Incubation temperature determines sex in many turtle species. Warmer temperatures produce females. Climate change affects turtle populations through this mechanism.
Nests face many threats. Raccoons, skunks, and foxes dig them up. Lawn mowers destroy nests in yards. If you find a nest, mark it and mow around it. Baby turtles deserve a chance.
Protect turtles and their nesting sites when possible.

Fireflies Begin Flashing
Late May brings the first fireflies in many regions. These beetles emerge from soil where they spent months as larvae. Adults live for only a few weeks. Their sole purpose is mating. The flashing patterns attract mates of the same species.
Different firefly species have different flash patterns. Some flash quickly, others slowly. Some fly high, others stay low. Learning patterns help identify species. Though honestly, most people just enjoy the light show without worrying about IDs.
Fireflies need moisture and darkness. They’re declining in many areas due to light pollution, pesticides, and habitat loss. If you still have fireflies, consider yourself lucky. Protect them by reducing outdoor lighting and avoiding lawn chemicals.
Watch for them at dusk near meadows and woodland edges. They prefer areas with vegetation. Open lawns don’t support many fireflies. Letting grass grow and keeping brush piles helps. Standing water in containers can breed larvae.
Kids love catching fireflies. It’s a classic summer experience. Just be gentle and release them quickly. Don’t keep them in jars overnight. They need to flash and mate. Their lives are brief enough without our interference.
The Firefly Atlas tracks populations through citizen science. Report what you see. Your observations contribute to conservation efforts.
Magic is returning to evening yards.

Dragonflies and Damselflies Emerge
May brings adult dragonflies and damselflies emerging from ponds and streams. These insects spent months or years as aquatic nymphs. Now they transform into flying adults. The emergence process is dramatic and vulnerable.
Freshly emerged dragonflies cling to vegetation while their wings harden. They’re soft and can’t fly yet. This takes hours. During this time, they’re vulnerable to predators. Birds, frogs, and spiders eat many. Those that survive become voracious predators themselves.
Adult dragonflies hunt mosquitoes and other flying insects. A single dragonfly can eat hundreds of mosquitoes daily. This makes them valuable for pest control. They’re also beautiful with metallic colours and intricate wing patterns.
Damselflies are smaller and daintier. They hold their wings together over their backs when resting. Dragonflies spread their wings flat. Both are ancient insect groups that have existed for millions of years. They’re basically flying dinosaurs.
Watch near water on warm days. Dragonflies patrol territories and chase intruders. Males are often brightly colored. Females are duller. Mating happens in flight or on vegetation. The connected pairs look like hearts or wheels.
Bring binoculars. Many dragonflies won’t let you approach closely. But bins let you admire their colours and patterns. Field guides exist for identifying species. It’s a whole hobby. Check Dragonfly Society of the Americas for resources.
Airborne predators rule the water’s edge.

Listen for Bullfrogs and Green Frogs
By May, many frogs finish breeding. But bullfrogs and green frogs are just starting. These species breed later than spring peepers and wood frogs. Their deep calls dominate ponds through summer.
Bullfrogs make the classic “jug-o-rum” sound. It’s deep and carries far. Males establish territories and call from open water. They’re aggressive toward other males. Fights sometimes happen with much splashing and bellowing.
Green frogs sound like plucked banjo strings. Their call is shorter and higher than bullfrogs. They’re smaller, too. Both species are common and widespread in eastern North America. Learning their calls helps identify them without seeing them.
These frogs eat pretty much anything they can swallow. Fish, insects, other frogs, small snakes, and even birds. They’re sit-and-wait predators with big mouths. Watching them hunt is entertaining. They lunge suddenly at prey with surprising speed.
Tadpoles from these species take over a year to transform. They overwinter as tadpoles and complete metamorphosis next summer. This long development makes them vulnerable to pond drying. They need permanent water, not temporary pools.
Visit ponds at dusk. Bring a flashlight. Frog eyes reflect light, making them easy to spot. Just listening works too. The chorus builds as night falls.
Warm evenings have a soundtrack.

Moths Are Everywhere
May nights bring incredible moth diversity. These often-overlooked insects outnumber butterflies by huge margins. Thousands of moth species exist. Many are spectacularly beautiful. We just don’t notice them because they fly at night.
Luna moths are famous. These large pale green moths have long tails and are stunning. Cecropia and polyphemus moths are also large and colourful. Seeing any of these silk moths feels special. They’re impressive insects.
Most moths are smaller and less obvious. But many are beautiful close up. Intricate patterns and colours are revealed. Pink, yellow, orange, and countless shades of brown and grey. Some look like bird droppings or bark. Others look like aliens.
Moths are important pollinators. Many flowers are specifically adapted for moth pollination. They’re also crucial food sources. Baby birds eat countless caterpillars. Without moths and their larvae, bird populations crash.
Attract moths with outdoor lights. A white sheet with a light shining on it works. Moths land on the sheet where you can photograph and observe them. This is called “mothing”, and it’s addictive. You never know what will show up.
The Moth Photographers Group helps with identification. Post photos to iNaturalist for ID help. You’ll be amazed by the diversity in your yard.
Night is busier than you think.

Wildflowers Shift to Summer Species
Spring ephemerals are gone by May. Now different wildflowers take over. These are plants that bloom in sun-dappled conditions or full sun. They’ll continue flowering through summer.
Wild roses bloom along roadsides and fencerows. Their simple five-petaled flowers smell wonderful. They’re important for native bees. Black-eyed Susans start showing yellow. Coneflowers prepare to bloom. These plants define summer meadows.
Dame’s rocket blooms in purple and white along roadsides. It’s actually not native but naturalised. There is debate over whether to consider it invasive. Regardless, butterflies use it. Ox-eye daisies create white fields. Again, non-native but established.
Native options include lupines, wild indigo, and spiderwort. These support more insect species than non-natives. Mountain laurel blooms in eastern forests with intricate pink and white flowers. In the western mountains, different species bloom at higher elevations.
Woodland plants shift, too. Solomon’s seal dangles white flowers under arching stems. False Solomon’s seal has flower clusters at the stem tips. Mayapples, which bloomed secretly in April, now have visible white flowers under their leaf umbrellas.
The cast of characters changes. Learn the new players.

Goslings and Ducklings Appear
May brings baby waterfowl. Canada goose goslings follow their parents in fuzzy yellow-grey groups. Mallard ducklings paddle behind their mothers. Wood duck ducklings leap from nest boxes in trees. These babies face numerous dangers, but seeing them is delightful.
Geese are very protective of goslings. Don’t approach too closely. Parent geese will hiss and might attack if you threaten their young. Give them space. Watch from a distance with binoculars if you want a closer look.
Duck broods are vulnerable to snapping turtles, large fish, and raptors. Mother ducks lose ducklings daily to predators. They often start with a dozen and end up with three or four. It’s harsh, but that’s nature’s math. High reproductive rates compensate for high mortality.
Wood ducks nest in tree cavities. Ducklings jump from nests within 24 hours of hatching. They leap from heights of 20 feet or more and bounce when they hit the ground. Then they follow their mother to water. This strategy seems insane, but it works for them.
Other waterbirds have babies, too. Coots, grebes, and moorhens all nest in May. Each species has different strategies. Some carry babies on their backs. Others let them swim immediately. Watching family groups teaches you about different parenting styles.
Keep dogs away from waterfowl families.

Notice Tree Flowers Falling
Trees that bloom in April shed petals and catkins in May. This creates carpets of flowers on the ground. It looks pretty, but it’s actually trees reproducing. Those falling petals mean pollination happened. Now, trees focus on fruit and seed development.
Cherry blossom petals create pink snow. Crabapple petals carpet sidewalks in white and pink. Catalpa trees drop large flowers. People complain about the mess, but this process is essential for tree reproduction.
Oak catkins fall, covering everything in yellow-brown chains. These are male flowers that already released pollen. Female flowers on the same trees are developing into acorns. You can see tiny acorns forming if you look closely at branch tips.
Maple trees drop their seeds, called samaras or helicopters. Kids love throwing these and watching them spin to the ground. Each samara contains a maple seed. Some will sprout next spring. Most will feed squirrels and birds.
These reproductive efforts in trees take enormous energy. That’s why most trees don’t produce heavy seed crops every year. Mass years happen periodically when many trees coordinate heavy seeding. This overwhelms seed predators, ensuring some seeds survive.
Look down while walking. The ground tells stories.

Garden Birds Visit Feeders Less
You might notice fewer birds at feeders in May. This is normal and not concerning. Natural food is abundant now. Birds prefer insects for feeding nestlings. Seeds and suet are backup options when insects aren’t available.
Caterpillars are everywhere in May. Trees are covered with them. Birds exploit this resource heavily. A chickadee pair feeds thousands of caterpillars to their nestlings. This protein-rich food helps babies grow quickly.
Some birds still visit feeders. Goldfinches eat seeds year-round. Orioles continue visiting orange and jelly feeders. Hummingbirds need sugar water. But overall feeder traffic drops dramatically compared to winter.
This is actually good news. It means your local ecosystem is healthy and provides natural food. Birds doing well on native insects means your area supports biodiversity. Take pride in that ,even if your feeder seems lonely.
You can help by avoiding pesticides. Caterpillars are what baby birds need. Those “pest” caterpillars on your trees are actually bird food. Let them be. Birds will control the population naturally.
Consider taking feeders down and cleaning them thoroughly. This prevents disease spread during quiet months. You can always put them back up in the fall.
Natural systems are working as designed.

Snakes Are Active Everywhere
May warmth brings peak snake activity. They’re hunting, mating, and moving through territories. You’ll encounter snakes more often now than at any other time. Most are harmless. All deserve respect and space.
Garter snakes hunt in gardens and meadows. They eat slugs, worms, and small amphibians. Black rat snakes climb trees, hunting bird eggs and nestlings. Water snakes bask on rocks near ponds and streams. These common species are beneficial.
Venomous snakes are also active where they exist. Copperheads hunt at night. Timber rattlesnakes bask on rock outcrops. Water moccasins patrol southern wetlands. Learn which venomous species live in your area. Know their appearance and habits.
Most snake encounters are harmless if you pay attention. Watch where you step when hiking. Don’t reach into areas you can’t see. Give snakes space to escape. They’d rather avoid you, too.
Snakes control rodent populations. A single rat snake can eat dozens of mice annually. They also eat ticks by consuming small mammals that carry ticks. Snakes provide ecological services we rarely appreciate.
If you find a snake in your yard, leave it alone. It’s passing through. Snakes don’t infest areas. They hunt and move on. Killing them removes beneficial predators. Most people who get bitten try to kill or capture the snake. Just back away.
Watch respectfully. Take photos. Appreciate them. Move on.

Everything Feels Green
By late May, the landscape is completely green. Trees are fully leafed. Grass is lush. Everything is growing rapidly. This green phase lasts through the summer. Right now it’s fresh and new. By August, it’ll look tired.
This green comes from chlorophyll. Plants are photosynthesising like crazy. Converting sunlight to energy. Growing leaves, stems, and roots. Storing energy for winter. The whole world is basically a solar panel factory right now.
Notice how many shades of green exist. New leaves are lime green. Mature leaves are darker. Different plant species have different greens. Some are blue-green, others yellow-green. Once you start seeing these differences, the landscape becomes less monotonous.
This green also means humidity. All those leaves are transpiring water into the air. May can feel muggy as plants pump moisture into the air. This creates afternoon thunderstorms. The water cycle is visible if you pay attention.
Appreciate this greenness. It won’t last forever. Fall will bring colours. Winter will bring brown. But right now, May is showing off photosynthesis in all its glory.
Green means life. It means growing. Green means energy flowing through ecosystems.
Breathe it in.

Slow Down and Enjoy
May is when I try to stop frantically documenting and start actually experiencing. April was chaos. June will be hot. May is perfect for just being outside without an agenda.
Sit under a tree and listen. Watch ants working. Notice clouds moving. Feel the breeze. This mindful observation is valuable even though you’re not identifying anything or checking boxes.
Nature watching isn’t always about knowledge. Sometimes it’s about connection. Feeling part of something bigger. Remembering you’re an animal in an ecosystem too. May weather makes this easy and comfortable.
Bring a book outside and read in the shade. Let nature be the background ambience. You’ll still notice things. A bird is landing nearby. A butterfly passing. Thunder building. You’re participating just by being present.
Take kids or pets outside. They teach you to notice different things. Kids find weird bugs. Dogs smell things you can’t. Their perspectives enrich your experience. Shared nature time builds relationships, too.
May is generous. It gives you time and comfortable conditions. Take advantage. Summer will be hotter. Fall will be busier with migration. Winter will be harsh. May is the sweet spot.
Get outside. Stay awhile. Just be.
What will May teach you?
