Birdwatching or birding is a form of wildlife observation in which the observation of birds is a recreational activity. It can be done with the naked eye, through a visual enhancement device like binoculars and telescopes, or by listening for bird sounds.
During the dry season (May to September) rain is rare, it's less hot and there are fewer mosquitos.
Breeding season on the Isle of Lunga (one of the Treshnish Isles) starts in the middle of April. To make sure to have thousands of them on Lunga Island I recommend a visit not before May. They stay on this island until the beginning of August. I went there at the end of June and besides puffins, I saw chicks from the guillemot, razorbill, and shag. The puffin chicks are hidden in the burrows and you may encounter them only when they leave the nest.
The bst time is during the dry season. June may also be a good option with fewer tourists and lower rates.
The dry season last from Dec. until April/May. Anyway this is one of the wettest regions in the world with 7 liters of rain each year. The climate is humid tropical. The driest month is March and the wettest is August.
The nesting season for the gannets lasts from August to March. Late summer you can spot how the chicks get fed. In the winter most of the gannets migrate to Australia.
The summertime is also the peak season from December to March. Weekends are more crowded due to beach visitors and surfers. Limited parking, therefore, come either early in the morning or late afternoon at weekends; mid-week and spring are less busy. More crowded on sunny days and very few visitors during cold, rough days.
Warmest months are in the summer from December until March often with pleasant temperatures around 20 °C at daytime and 10-12 degrees in the night. The coldest months are in the winter from June to August, but it's not freezing. Most rainfall in winter but it already starts in May with the peak in July. Driest months are in the summer from November to February/March. The best months for swimming between the flags are January until March, but the sea temperature is still lower than 20 °C.
Be prepared for the windswept coastline and bring a warm jacket. If you are downwind, you experience the penetrating smell of gannet poo.
It is always said the morning is the best time of the day but we were very successful in the afternoon until the evening. The most important thing is being patient and quiet.
Crowds and Weather:
Expect more visitors in summer from December until February and during weekends. March is a good month still warm, less crowded and a bath in the sea is possible. Most precipitation in winter.
September until December one hour before dusk wait at Murrays Beach and you may spot groups of little penguins swimming back to Bowen Island for feeding.
The island is a successful breeding colony with roughly 5.000 breeding pairs. Winter (June to August): Yellow-tailed black cockatoos are more common in winter due to the mild climate. Black-browed albatross and gannets can be spotted from the cliffs more often in winter. You see the silvereye in large flocks and a migratory silvereye from Tasmania with reddish sides. The tawny frogmouth can be spotted in the night.
The breeding season is from November to July. Nesting time is the 'only' time they spend on land which is roughly 290 days each year.
WEATHER: The dry season is from May until October. The north and east coast get more rain than south and west which is the leeward side. Even in winter, when it's 'rainy' season from November to March you don't have to worry: Mostly showers are short and the sun returns quickly.
CROWDS: Low season in spring between mid-April and mid-June as well as in fall from September to November. Busier during the "Golden Week" in Japan end of April until beginning of May. Busy and increasing rates in summer, during Christmas, New Year's Eve and on Independence Day.
