Passing through Mumbai airport last week I saw, for the first time, crows inside the huge building. I have seen pigeons inside buildings before, but this was the first time I saw crows. An airport terminal is a closed structure, so it is somewhat strange to see birds inside. One wonders how they get in.
I was reminded of the ingenious Spanish bird’s net: a large net strategically placed to exclude birds. Spanish buildings are open to the air, as Indian buildings are, and for the same reason. Clever circulation of air can cool buildings. A typical Spanish style is a structure built around one or more open courtyards. I noticed that there were seldom any birds inside these buildings. The reason is a net stretched right across the opening at the level of the roof. The mesh is small enough to exclude even the notorious Spanish sparrows!
We had not planned to do any bird-watching while we were in Spain. The Family had not even carried her binoculars with her. When I saw a few sparrows raiding the ground around a cafe in Madrid for crumbs, I took photos because I was not doing anything else. Imagine my surprise when I looked at the photos and found that they did not resemble any sparrow I have seen before. Thumbing through my field guides I came to the conclusion that the species is not found in India. Further search makes me think I might have seen immature Iberian rock sparrows (Petronia petronia). An adult would show a distinct yellow patch at the throat, and a more well-defined light streak above its eyes. Notice the thick yellow beak and the long grasping toes; these are characteristic of both the adult and the juvenile.
This surprise made me go back to a photo I had taken in the Alhambra of a sparrow nesting in a hole in a wall. It wasn’t the same. In fact this was another sparrow which I had not seen before, and which cannot be found in and around India. Another search led me to think that this is the so-called Spanish sparrow (Passer hispaniolensis). The streaks on the back and the markings around the eye distinguish it from the house sparrow. By the markings that I see, this individual is a female. I took this photo originally because of that immense gape of the nestling.
Two lifers! Even without looking for them. Sometimes one gets lucky.
I’ve seen three kinds of sparrows in India: the common house sparrow, the Eurasian tree sparrow, and the russet sparrow. This almost doubles the count. I would have to travel across central Asia and Africa to see the remainder of the dozen or so old-world sparrows.
