Amazing photos- Mt Kinabalu is a fabulous place for birding; I have been several times and will return! Do you mind posting details of where you stay, car hire etc? I normally stay in the park itself but this has become an expensive option in recent years. I didn't have a car last time I visited but the drivers were very good about giving a hitched lift up to the Timpohon gate. There is a US university studying the Mt Kinabalu birds, hence all the colour rings. The students are worth talking too if you encounter them. They directed me to a few birds I was keen to see.
