Thanarok kindly invited me to his home and we enjoyed a true Thai meal at a restaurant by the river.
Thank you Thanarot! Very yummie! In the morning we did general birding in the wetlands surrounding Beung Borapet (240km North of Bangkok) and saw a lot of birds including a roosting Savanna Nightjar, Glossy Ibises and plenty of Streaked Weavers.......We then sat down to view the trees he had seen the Cuckoos in. After 2 and a half hours and no bird I thought; 'better pack up, bet that will bring it in, a bit sarcastically'. Before we got our stuff together in the car I gave a last scan and my eyes fell on the Cuckoo. They had finally arrived. A wonderful lifer and classy bird. It might be easy in Africa and India but over here it is a mega rarity.
(never mind I had to endure a 6 hour drive (240km) back to Bangkok in insane traffic)
