Parc Lalla Hasna is a large city park near the city centre of Marrakech. It is located right next to the large Koutoubia mosque and the large El Fna square. It's a great place to observe many species of songbird in this very green part of the city. The park is divided by several pathways all leading to the fountain in the center of the park. The rest of the park contains many trees, bushes and flowerbeds.
The (palm)trees are used by common species of songbird, like Common Bulbul, Spotless Starling and House Bunting. Other scarcer species, like Great Grey Shrike and Western Olivaceous Warbler, can be found in especially the more quiet areas near the edges of the park. If you're lucky, the very beautiful Moussier's Redstart might show itself!
Flocks of swifts, being mainly Pallid Swift and Little Swift, tend to hang around the mosque tower and also over the park. Sometimes a Common Swift or Alpine Swift can be found within these flocks.
Also predatory birds can be observed above the park, like Booted Eagle and Black Kite. Eurasian Kestrel can be found perching on (mostly) palm trees.
The area is easy accessable and the park is free to enter. You can just walk around on the pathways.
