American Crocodile returns to swollen estuary

July 14, 2026Costa Rican seasonal moist forests

(Crocodylus acutus) appeared in the estuary this week as tides ran 17 centimeters above prediction, pushing the brackish zone farther inland — the kind of tidal anomaly that pulls these reptiles from deeper channels into the wider, wetter margins they depend on.

Hunted nearly to extinction in this region during the last century, they have rebuilt slowly across decades. Two research-grade sightings in the past six months suggest the population is still recovering, but each swollen July estuary offers temporary habitat that may allow them to venture upstream into areas that were empty for generations.

Wet-season sphinx moths return to work the deep flowers

July 23, 2026

The forest-interior lepidoptera community has shifted entirely with the rains. The sun-loving sulphurs, swallowtails, and queens that dominated the dry months have withdrawn, replaced now by owl-butterflies moving through the shaded understory since late June, working the forest edges into early July, and — most tellingly — an (Eumorpha anchemolus) logged on July 15. These large hawk moths vanish during the dry season and return with the rains to work the night flowers. Their arrival marks one of the forest's clearest seasonal pulses.Sphinx moths carry an outsized ecological role here. With tongues longer than their bodies, they are the primary pollinators of deep-tubed flowers that no hummingbird or other insect can reach — making their return as essential to the forest's reproductive cycle as the rains themselves. Over six months of observation, four sphinx moth species appeared during the dry months, but only the Anchemola Sphinx during the wet season's peak. Their presence, alongside the shift to shade-dependent butterflies, is a quiet affirmation that the forest corridor remains connected enough to support the full community of specialists, not merely the generalists that persist in fragments.

Yellow toads (Incilius luetkenii) are calling in chorus as the rains settle…

June 30, 2026

(Incilius luetkenii) are calling in chorus as the rains settle in — the most abundant amphibian sightings recorded here over the past three months. These small toads breed in synchronized pulses timed to the wet season's onset, their voices rising with the first consistent downpours.On the Nicoya Peninsula, farming families have long read these calls as a planting signal, timing their crops to the toad's rhythm. That folk knowledge rests on close observation of a real ecological connection: the toads' breeding chorus marks the point when soil moisture and insect abundance align for successful reproduction. The rains are holding, and so are the toads — both signals in sync, as they have been for generations.

Hawksbill turtles nest along the summer beach

June 27, 2026

The beach near Nandayure goes quiet as the light drops. The dry season birds have pulled back into the forest edge, and the surf takes over the soundscape. This is the hour the hawksbill turtles come ashore.Hawksbills are smaller than the leatherbacks or greens that share these Pacific waters. An adult female weighs around eighty kilograms, and her shell is narrow and tapered at the front, with overlapping scutes that give it a ridged, shingled look. Her beak is pointed and slightly hooked, shaped for pulling sponges off coral heads. She spends most of her life at sea, feeding in the reef systems offshore, but summer draws her back to this stretch of sand. She navigates by the earth's magnetic field, detecting both the intensity and inclination of the field lines, and she returns to the same beach where she hatched. Not the general region. This beach. Researchers have documented females nesting within meters of where they emerged decades earlier.She comes ashore after dark. She moves across the wet sand slowly, pulling herself with her front flippers, pausing to rest. Above the tide line she begins to dig. First a wide body pit, scooped out with all four flippers. Then, from the back of that pit, the egg chamber: a flask-shaped cavity about forty centimeters deep, excavated with her rear flippers working in alternating scoops, one at a time, each one curling and pressing the sand out to the side. The chamber takes twenty minutes to an hour to dig, depending on the sand. When it is finished she lays between one hundred and two hundred eggs, each one soft-shelled and slightly smaller than a golf ball. She covers the chamber, filling it and tamping the surface, then sweeps sand across a wider area to obscure the site. By the time she returns to the water the work is done.The eggs incubate in the sand for about sixty days. The temperature inside the chamber matters: cooler incubation produces more males, warmer produces more females. The nest is not tended. The female may return to this beach three or four more times this season, laying another clutch every two weeks or so, but she does not come back to the eggs she has already buried. When the hatchlings emerge they dig up through the sand together, usually at night, and orient toward the ocean by moving toward the brightest horizon. On a dark beach with no artificial light, that is the sea. Light from buildings or roads pulls them in the wrong direction, and many do not make it to the water.Hawksbills are critically endangered. Their populations have dropped sharply over the past century from hunting, egg collection, and the destruction of the coral reefs where they feed. The sea almond trees you may notice at the upper edge of the beach are an introduced species, non-native to this coast, and their spread can alter the slope and shade of the upper beach in ways that affect nest temperatures. The pressures on this animal are real and have accumulated over a long time. But the turtles are still here. On beaches like this one, nesting females still come ashore in summer, still dig their chambers by feel in the dark, still return to the same sand they came from.
