Hummers 2

The hummingbird feeder on our balcony in Bucaramanga is now a success and we get regular visits from 4 different species.

The Indigo-capped Hummingbird (Amazilia cyanifrons) is the most frequent, the most aggressive with the other hummers, and they sometimes buzz near our faces as if they're also trying to intimidate us! They are not in the least bothered by my presence and I can gently touch them with my finger. They are also very impatient; when I changed the sugar-water, one of them could not wait for me to hang it outside, and came into the apartment and sat on the top to wait (it was upside-down) while I walked outside! Very cheeky birds....

The Rufous-tailed Hummingbird (Amazilia tzacatl) is very common around the city.

White-necked Jacobin (Florisuga mellivora) are slightly larger. They tend to hover when feeding rather than perch. One of them at least decided to stand up to the bullying of the Indigo-capped and the dog-fights lasted several minutes.

Black-throated Mango (Anthracothorax nigricollis) are also common here but took some time to arrive. Now they are now regulars. This is a male.
And this is a female. She's got a very distinctive white throat and belly with a vertical black stripe which makes them unmistakable. The tail is also very colorful when fanned.

I've noticed a great variation in numbers of visiting males & females of the different species. There seem to be more female Mangoes than male.  However, despite seeing many different male White-necked Jacobin, I've yet to see a female. I can only put this down to nesting activities at the moment - the females do all the work of rearing the young, who are fed insects. Perhaps we'll soon see more females, but I've much to learn about the seasonality, or lack of it, in Colombia.

There are 162 species of Hummers in Colombia. Several of these live in and around the city, but we've not seen them on the feeder yet. I'm hoping they'll find it soon.
