I have visited Masai Mara before. It is always a true highlight of any visit to Kenya. This visit wasn't different. The multi-sensual experience of being within a sea of animals, with the sounds, smells, action, diversity, action - is unparalleled in Kenya, IMO.
Our location in Masai Mara wasn't ideal actually. Due to low availability of accommodation options at central locations, we stayed at Mara Sopa Lodge, located at the far northeast corner of the park. The lodge itself is lovely, but it's location is less ideal, from a classic 'safari' POV. It's a rather long drive through sub-optimal habitat to reach the heart of the park where the large numbers of animals are. That said, there were good birding opportunities in the open forest/bush on the hills surrounding Sopa Lodge, a habitat that we spent insufficient time in. The track heading up from Mara Sopa Lodge towards Sekenani Gate, and down towards Oloolaimutia Gate provided poor photos depicting enjoyable encounters with good birds.
Not my best photo of the trip, fantastic bird - White-headed Sawwing:
