What to look for in nature in Rhode Island this May

Which birds arrive in Rhode Island in May, and when?

• Orioles, tanagers and grosbeaks

  Through the month; orchard orioles usually arrive by mid-May · Park edges, old cemeteries and neighborhood trees in bloom, plus open woodland

  Audubon names yellow warblers, Baltimore orioles, scarlet tanagers and rose-breasted grosbeaks among the birds that fill in during the migration. Baltimore orioles return in May, when flowering trees are open. The female weaves a sock-shaped nest that hangs from a deciduous branch. Orchard orioles show up in mid-May and often leave again by mid-July. The rose-breasted grosbeak travels late in spring and at night, and its song sounds like an improved robin, according to the National Audubon Society’s field guide. To draw orioles to a yard, Audubon suggests planting flowering trees and setting out grape jelly in a cup or a skewered orange.

• Ruby-throated hummingbirds

  Males arrive ahead of females; follow the Journey North maps for the front · Gardens, feeders and flowers with long tubes, such as columbine

  Journey North collects sightings from volunteers and draws maps that show the front of the hummingbird migration moving north each spring, so check the map before you hang a feeder. Males head north before females. If you keep a feeder, use plain sugar water without red dye, clean it often, and hang it away from windows and out of reach of cats, as the National Audubon Society advises.

• Warblers and vireos

  Mid-May is often the heart of the movement · Fisherville Brook in Exeter, Rome Point in North Kingstown, Prudence Island and the shrubby edges of the refuges

  Audubon has hosted warbler workshops and field visits at Fisherville Brook Wildlife Refuge in Exeter and at Rome Point in North Kingstown, and a 2018 Audubon article expected Prudence Island’s spring migration to be in full swing by mid-May. Look for small, quick birds in the new leaves, and learn a few songs first, because the leaves hide most of them. Birds that nest here, such as the American redstart and the prairie warbler at Ninigret, stay all summer. Others pass through for a few days on their way to forests farther north.

• The last of the northbound sea birds

  Early and mid-May · Bays, ponds and rocky points

  While songbirds fly in, scoters, mergansers and loons head out for northern nesting grounds. Audubon lists harlequin duck, common goldeneye and bufflehead among the ducks that leave, and Audubon’s birding guide says purple sandpipers feed on the rocks at Sachuest Point from late November to May, so the early days of the month are the last good chance to see them this season.

Where are the best places to watch Rhode Island’s migrants and nesting birds?

• Norman Bird Sanctuary, Middletown

  Spring through summer · Aquidneck Island

  Audubon’s state birding guide calls the sanctuary especially good for birds in migration and lists willow flycatcher, black-and-white warbler, rose-breasted grosbeak, bobolink and Baltimore oriole among its nesters. The sanctuary’s own events page lists guided bird walks every other Sunday morning and nature walks on Wednesday afternoons; check it for the 2027 schedule and any fee.

• Trustom Pond and Ninigret refuges, South County

  All month · South Kingstown and Charlestown

  Trustom Pond’s 787 acres of field, shrubland, pond, dune and beach hold willow flycatcher, warbling vireo, yellow warbler, bobolink and orchard oriole as nesters, according to Audubon’s guide. Part of the barrier beach is closed in nesting season to protect piping plovers and least terns, so ask at the contact station. Ninigret’s salt pond shore draws shorebirds in spring and fall, and blue-winged warbler, American redstart, prairie warbler and cedar waxwing nest there. Trustom Pond keeps daylight hours, sunrise to sunset, and each refuge page lists its closures for hunts.

• Sachuest Point, Middletown

  All month · The rocky shore and the salt marsh by Third Beach

  Migrant shorebirds use the rocky shores and beaches, and Audubon says saltmarsh sparrows nest in the marsh by the Third Beach parking lot. The refuge warns that wet rocks along the shoreline are slippery and can be dangerous, and storm waves sometimes close the access road.

• Prudence Island

  Peak migration in mid-May, according to Audubon · Narragansett Bay, reached by ferry

  The Narragansett Bay National Estuarine Research Reserve manages 63 percent of the island and its surrounding waters, with a learning center, hiking trails, fishing spots and birdwatching areas. Audubon has run spring birding trips there in past years, so look for a 2027 trip on its calendar.

• Block Island

  All season · Off the state’s southern shore

  The Block Island National Wildlife Refuge is home to two breeding species that are federally listed: the threatened piping plover and the endangered American burying beetle. The Nature Conservancy’s island program protects nearly half the island, manages more than 2,000 acres of wildlife habitat, and sells a $2 map of 28 miles of walking trails. The Conservancy and the Block Island Conservancy co-sponsor free guided nature programs through the year.

• Great Swamp Management Area, South County

  Late May for breeding birds · Swamp forest and wetlands

  Audubon’s guide lists yellow-billed cuckoo, eastern whip-poor-will, veery, hermit thrush, ovenbird and several warblers as spring nesters at the swamp. The area is open to hunting, and the spring turkey season runs into the third week of the month, so see the safety notes below before you go.

What hatches on Rhode Island’s beaches and nest platforms in May?

• Osprey chicks

  Eggs usually begin to hatch in late May · Platforms and poles over water; ASRI’s monitors watch about 150 active nests

  According to DEM’s fact sheet, a female typically lays three eggs during April and sits on them for about 38 days, which brings the first hatch at the end of May. The young fledge after about 50 days, and then depend on their parents for another eight weeks. Rhode Island was down to two nests in 1967 because of DDT, and the Audubon Society of Rhode Island has run the monitoring program since 2010, with volunteers watching nests from April to August. An active nest with eggs or chicks is protected under the Migratory Bird Treaty Act, so keep your distance, and phone the Division of Fish and Wildlife if a nest on a pole or building becomes a problem.

• Piping plover chicks

  Eggs hatch between late May and early June · Roped-off nesting areas on state and refuge beaches

  Incubation lasts 25 to 28 days, shared by both parents, and a hatched chick leaves the nest within hours and feeds itself. The chicks reach the wrack line to find small invertebrates, because the parents do not feed them. Federal biologists say the young can fly 25 to 35 days after hatching. A 2020 state release counted 80 pairs in Rhode Island in 2019, up from 10 when the species was listed in 1986. It asked beachgoers to keep their distance, take trash and food scraps home, and fill in sandcastle moats and holes in which a small chick could be trapped. The same release listed a dog ban from April through September at state beaches, federal refuge beaches and the Nature Conservancy’s Goosewing Beach Preserve, so check the rules posted at your beach.

• Terns on the open beach

  Nesting through June · Barrier beaches in South County

  The state release also named least terns among the species that nest on Rhode Island beaches, and Audubon’s birding guide lists common terns at Ninigret. Terns lay on bare sand with almost no nest, which is why beach closures are posted in May. A bird that dives at your head is telling you to back away from a nest.

• American oystercatchers

  Nesting now; chicks later in the season · Beaches southwest of Narragansett Bay, islands in the bay and northwest Block Island

  A 2019 update from state and refuge biologists puts most of the state’s oystercatcher pairs on natural islands in Narragansett Bay, where nobody tracks how many chicks survive. Up to 10 pairs nest on Sandy Point Island, which the Fish and Wildlife Service leases from Avalonia Land Conservancy and where dogs are prohibited. Block Island was down to a single pair in 2019, after holding as many as five. Surveys and posting of old nest sites start in late March or early April, and staff check nests one to three times a week.

Which animals are crossing Rhode Island’s roads in May, and what should I do?

• Painted and snapping turtles

  Aquatic turtles leave the water in May and June to nest · Roads near ponds, rivers and wetlands, and sandy or loamy soil in fields, open woods and lawns

  Audubon says the eggs laid this spring hatch from late August to early September, and the hatchlings cross roads too. The Wildlife Clinic of Rhode Island took in 44 turtles struck by cars in 2024. When stopping is safe, carry a turtle a few feet past the edge in the direction it was already facing, since it may not be going to water. Lift it with a hand under each side of the shell, never by the top shell or the tail. Do not pick up a snapping turtle: guide a large one across with a stick or a broom, or get help.

• Box and wood turtles

  Crossing again after nesting · Woods, fields and wet meadows

  These land and semi-aquatic turtles cross roads again on the return trip. Native turtles should stay wild, and Audubon notes that removing any native reptile or amphibian from the wild is prohibited in Rhode Island. Audubon also sells yard signs for residents near ponds and wetlands, for display in May, June, August and September.

• White-tailed deer fawns

  Does give birth in late May or early June · Lawns, field edges and thickets

  The state’s deer fact sheet says a fawn can stand within an hour of birth and wears a spotted coat for camouflage. For the first two weeks the mother leaves her fawn alone to feed and returns only now and then to nurse, so a fawn alone is normal. The sheet says never touch or approach a fawn. If a fawn is on a road or injured, call the Wildlife Rehabilitators Association of Rhode Island at (401) 294-6363, the number printed in the sheet. Young does usually have one fawn, and older does may have twins or triplets.

Do horseshoe crabs come ashore in Rhode Island in May?

• Guided looks at spawning

  The Audubon Society of Rhode Island listed expeditions in May 2026; check for 2027 · Conimicut Point in Warwick and Napatree Point in Westerly

  The Audubon calendar for May 2026 included a Horseshoe Crab Expedition at Conimicut Point and another at Napatree Point. Audubon had not published 2027 dates yet, so look at its calendar closer to the month.

• Why shorebirds care

  May at Delaware Bay · Delaware Bay, the largest staging area for shorebirds on the Atlantic Flyway

  Crab eggs are an important food for migrating shorebirds. The Fish and Wildlife Service says Delaware Bay is the last Atlantic coast stopover for roughly 50 to 80 percent of the red knots heading to the Arctic, and that birds there can nearly double their weight in about two weeks. Managers allow only male crabs of Delaware Bay origin to be harvested in 2026 and 2027, with a limit of 500,000, and no females, according to the commission. The commission adds that Delaware Bay holds the world’s largest spawning population, and Rhode Island’s crabs are a smaller part of the coastwide picture.

What is blooming in Rhode Island’s woods in May?

• Pink lady’s slipper

  May, June and July, according to Go Botany · Acidic soils in forests, swamps and bog edges

  One nodding, pouch-shaped pink flower rises on a stalk above a pair of basal leaves. Go Botany explains that bumblebees enter through a slit in the pouch and leave by an opening at the back, and it warns that touching the floral bract can irritate some people’s skin. Leave the plant where it grows.

• Wild columbine

  Dates vary; the Among Rhode Island Wildflowers guide groups it with the early bloomers · Rocky woods and ledges

  Pink-red flowers, sometimes yellow, hang downward, each with long nectar spurs, and long-tongued insects visit them. Go Botany says it grows in rocky and wooded places, including cliffs and ledges. No source gives a firm Rhode Island bloom week, so treat the first half of May as a good time to look.

• Common blue violet

  Flowers open about when the leaves come out · Woods, meadows, lawns and roadsides

  The flowers hang downward on stalks, with five blue to purple or white petals. Go Botany notes that ants carry the seeds, which are attached to small food bodies. Violets that spread in a lawn are a good nature journal subject.

What is May weather like in Rhode Island, and what are the hazards?

Is the last spring freeze over in Rhode Island by May?

How much daylight does Rhode Island gain in May?

What can you see in the Rhode Island night sky in May 2027?

• Eta Aquariid meteors

  Best mornings are May 5, 6 and 7 · The last hour or two of darkness before dawn, looking toward the southeast

  In Sea and Sky’s listing the maximum falls overnight from May 6 into May 7, and 2027 is rated an excellent year because no moonlight interferes. Its figure is roughly 30 meteors per hour at best for northern observers. Rhode Island lies north of the ideal spot: Aquarius, where these meteors seem to originate, climbs only a little before the sky starts to brighten, so count on fewer. In Providence, civil twilight begins at 5:05 a.m. on May 6, so go out early and give your eyes 20 minutes.

• Venus and Saturn at dawn

  Friday, May 7, with about a degree between them on the mornings of the 6th and 8th · Very low in the east before sunrise

  Our own calculations put the closest approach of Venus and Saturn on May 7, at a separation near 0.6 degrees. Both lie in Pisces and hug the horizon, standing about 3 to 6 degrees up thirty minutes ahead of sunrise. Binoculars and a clear view east are needed. Venus outshines Saturn by a wide margin (magnitude -3.9 against +0.7). This is a difficult sight, though a patient observer can catch it.

• Jupiter in the evening

  All month; the first-quarter Moon is near it on the evening of May 12 · High in the sky after dark

  Jupiter is still the bright evening planet. By our computation it sets about seven hours after dusk on May 1 and only a little over four hours after dusk by June 1, so evenings are the time to look. On May 12 the Moon, close to first quarter, passes about 1.2 degrees from it.

• Mercury’s best evening of the year

  Greatest eastern elongation Friday, May 28, at 9:14 a.m.; look on May 27 and 28 · Low in the west-northwest, 45 to 90 minutes after sunset

  Mercury reaches 22.9 degrees from the Sun, according to Sea and Sky. The U.S. Naval Observatory puts Providence’s sunset on May 27 at 8:10 p.m., so look between about 9 and 9:40 p.m., with an open view of the horizon and binoculars to help. By our own figures, the best evenings run from about May 12 to June 5. Mercury lingers in the evening sky into early June but fades fast after mid-month.

• The Flower Moon, a seasonal Blue Moon

  Full Thursday, May 20, at 6:59 a.m.; the best evening is Wednesday, May 19 · Rising in the east after sunset

  The May full moon is the Flower Moon. Sea and Sky also calls it a Blue Moon in the seasonal sense: it is the third full moon in an astronomical spring that holds four, reckoned from the equinox in March through the solstice in June. It is not a Blue Moon by the calendar-month definition, as there is only one full moon in May. Because the full moment comes at dawn, the Moon looks round on both evenings. In Providence on the 19th it rises at 7:46 p.m., 17 minutes before the 8:03 p.m. sunset.
