Most birders will want to be up before dawn to head out to the birding location so how do you find out when sunrise is?
TIME & DATE WEBSITE
Type in the nearest town. In this case I will search Santa Marta, Colombia to get an idea of sunrise & sunset in El Dorado Reserve. Here are the results for March 2016. You can check any month and year with the drop-down boxes. Looks like if you want to see Santa Marta Parakeets, you will need to leave the lodge by 5am to be in position by 6am. If you want to try for the parakeets coming in to roost for the night, be in position by around 3pm to maximize birding time as this location is up a very bumpy road so you need to take your time.
