Season

Birds Wintering waterbirds and passerines join resident endemics. Fruiting trees and seasonal flowers offer photography opportunities. Taiwan Thrush remains an exceptionally difficult target, even in winter. Taiwan Shortwing and Taiwan Cupwing are very shy and especially hard to find in December–February.

Weather Central and southern routes are often relatively dry; the north and northeast can be wet. January–March can be very cold. Ice may affect the road near Hehuanshan’s 3,275-metre Wuling pass.

Birds Winter visitors remain, and early spring migration may begin. Resident endemics are still a reason to visit, but Taiwan Shortwing and Taiwan Cupwing can be particularly elusive.

Weather Central and southern routes are often relatively dry; the north and northeast can be wet. Cold spells can continue through March, with possible ice around Hehuanshan’s 3,275-metre Wuling pass.

Birds Resident birds become more vocal as breeding activity begins. Spring migrants arrive while winter visitors gradually leave, changing the mix through the month.

Weather Spring rain increases, before the main May–June plum-rain season. Cold spells are still possible; ice may affect high mountain roads around Hehuanshan’s 3,275-metre Wuling pass.

Birds Breeding residents become active, spring migrants continue through Taiwan, and the Lanyu Island season begins. April also starts the main Taiwan Bush Warbler window. Fairy Pitta usually arrives in the last week of April, with variation between years.

Weather Warm, changeable spring weather. Allow for rain; the main plum-rain period follows in May–June.

Birds As spring migration winds down, resident breeders and summer visitors take centre stage. Fairy Pitta is in its main season; Oriental Pratincoles and Little Terns are also breeding.

Weather May is increasingly hot in the lowlands. The main plum-rain period usually starts around mid-May, with potentially prolonged or heavy rain.

Birds Fairy Pitta and summer breeders remain active. In our guiding experience, June offers the best chance of seeing all Taiwan’s endemic species on one trip. Every few years, we locate an active Taiwan Thrush breeding site, making this exceptionally elusive species easier to find in that particular season. It is never assured.

Weather Plum rain can continue through mid-June. From late June through July and August, afternoon thunderstorms become a typical summer pattern; lowland birding is hot and humid.

Birds Some late breeding activity continues. Mountain forests offer a change from the lowland heat, while summer birding on Lanyu Island remains an option.

Weather Hot and humid, with summer afternoon thunderstorms. Start early and leave room to adjust the route as storms develop.

Birds Southbound shorebirds begin returning to coastal wetlands. Resident and summer birds still feature, with the first signs of autumn migration.

Weather Hot and humid, with afternoon thunderstorms and typhoon risk. August–October is the typhoon-planning window used in this guide.

Birds After breeding, resident birds are generally quieter, and most winter visitors have not yet arrived. Autumn migrants and migrating raptors provide the main seasonal interest, including Chinese Sparrowhawks. September closes the main Lanyu Island and Taiwan Bush Warbler windows.

Weather Typhoons can affect travel, and lowland days may still be hot. Northeast monsoon conditions can begin to develop later in the month.

Birds Kenting’s autumn raptor migration is the highlight, especially Gray-faced Buzzards. Other autumn migrants continue through Taiwan while resident birds are quieter than in the breeding season. Sun Link Sea (Shanlinxi) is good for mid-elevation bird photography.

Weather The northeast monsoon becomes more influential in northern and northeastern Taiwan. October remains within this guide’s August–October typhoon-planning window.

Birds Wintering waterbirds and passerines arrive, alongside resident endemics. Late autumn migration can continue, depending on the bird group and the year.

Weather Central and southern routes are often relatively dry. The north and northeast can remain cloudy or wet under the northeast monsoon.

Birds Winter visitors, fruiting trees and seasonal blossoms create photography opportunities. Taiwan Thrush is still exceptionally elusive; occasional winter records do not make it a dependable target. Taiwan Shortwing and Taiwan Cupwing are very shy, skulking birds and particularly difficult in December–February.

Weather Central and southern routes are often relatively dry, while the north and northeast can be wet. High mountain mornings and nights are cold.
