Colombia is quite different from Cost Rica in terms of good birding options right around Bogota/Medellin. There aren't any birding lodges within a couple hours of Bogota unfortunately and the various birding sites mostly all require a couple hours drive to get to/between. Basing yourself in a hotel in Bogota means 2-3hours of driving each way every day to get to most of the birding sites.
If you are set on Colombia I would suggest Medellin and going to the Chestnut-capped Piha Reserve - 4hr drive but you can do some birding along the way and with 5 days spending a half day at either end in transit isn't so bad. The lodge is simple but birding there is exceptional though the trails are a little steep in places but as long as you have reasonable mobility they shouldn't bee too difficult. The local forest guard (assuming it is still Jose) knows his birds very well.
Another option from Medellin would be Rio Claro Reserve which is closer but it's a bit more touristy (rafting, swimming in the river etc) and can be quite busy on weekends.
If you're open to it, I would suggest your best bet may be Ecuador and going to one of the plethora of lodges in the Mindo area which is only a couple hours from Quito.
