Yes, as per the park website look for PARK_FREE_WIFI to connect to. Not sure where around the park the transceivers are.

Yes - as per the Park website there is wifi on the network PARK_FREE_WIFI

Updating my previous answer - according to the WRS website (WRS own the Zoo, Night Safari, River Safari and Bird park) - the Bird Park move is now scheduled to 2022, to coincide with the opening of the west arrival node in the Mandai development.

Yes. It's better if you buy the tickets for the Singapore Zoo, Night and River Safari, Jurong Park and the night shows all at once. Buy it as a package. It runs a little cheaper and you have a few days to finish it all and stay as long as you want. It's worth it. You can buy this package directly from them. Just go to their website.

I believe they have 2 shows one in morning and one afternoon, sorry cant remember exact times but if you get there around 9:30am it is best time as it start to get pretty warm in afternoon

Basically, the park has admission or entry fee at around 30 SGD, providing access to all areas in park. The standard ticket excludes the train ride inside park. However tickets can also be purchased including the tram rides. Tickets can be booked beforehand online or can be bought at location. Now as you wish to focus only on birds, as a bird enthusiast myself, I highly recommended to visit the Wings of Asia section and the bird feeding session at Pelican cove. Enjoy your visit !!

Both are interesting & worth seeing. For kids the birds show at Pools Amphitheatre will be a hit.

Hi! we were there in Singapore for seven days and there was a forecast of rain for every day but it did not rain at all on five days. On other two days it was just a drizzle. So you can be hopeful. If it just a little drizzle, umbrellas will suffice, if there is a kid with u, pack a rain coat. but the park is completely outdoors and the shows too. reach early because normally it rains in late afternoon.

Nearest MRT station is Boon Lay as others have said. Then you can take 194 to the bird park. It is only a few stops away and if you are changing from MRT, it will only cost you less than 10 cents for the bus journey due to the discount. We spent less than SGD 2 per person from Orchard to bird park using public transport.

Sorry, both are 20km apart and the parks are too big to cover in a single day. However you can cover Singapore Zoo, River Safari and Night Safari in a single day and it will be too tiring unless you can manage. You can book tickets at the WRS and use DBS or POSB credit cards if you know a friend and get 15 percent discount. There are multiple park tickets as well for cheaper price as compared to individual. Sorry as can't give link here. You can visit WRS website.
