The Resilient Pitangus Sulphuratus




Do you recognize this proud feathered fellow on the left? If you tell me you've never seen such bird, and you live or have been to somewhere on this Planet, from the tropics to the equator lines, I will tell you that there is a strong possibility that at least one of this type has already seen you.

Pitangus sulphuratus, the bird's scientific name, derives from pitanga (surinam cherry) fruit and from its sulfur yellow belly color. It has a popular and onomatopoeic name in different languages and countries because of its exuberant BEE-tee-WEE call; in Portuguese: bem-te-vi (I saw you well), in Spanish: bien-te-veo (I see you well); in French: qu'est ce (what is...), in German: Schwefeltyrann (sulfur tyrant), in Japanese, in Russian and so on....Of course, in English, it's the great kiskadee.


The great kiskadee is a conspicuous bird. It is almost omnivorous and hunts like a shrike, or flycatcher, waiting on an open perch high in a tree to sally out to catch insects in flight, or to pounce upon rodents and similar small vertebrates. It will also take prey and some fruit from vegetation by gleaning and jumping for it or ripping it off in mid-hover, and occasionally dives for fish or tedpoles in shallow water; making it one of the few fishing passerines.

This alert and aggressive bird uses its strong
and maneuverable flight as a good effect when it feels annoyed by raptors. Even much larger birds are attacked by the great kiskadee; usually by diving down or zooming straight at them while they are in mid-air.







The great kiskadee is commonly used in the control
of invasive species and is of large importance for
sowing seeds in urban areas.

The bem-te-vi is the most popular bird in Brazil. Maybe all along Latin America, as well; for it can be seen in most biomes and urban sites. Also, its amazing adaptability seems to be an infinite source for scientists.

I personally have good experiences with bem-te-vis. One of them is for their having killed my problems with my circardian cycle.

Daylight saving time ended yesterday in many states of Brazil, and friends were commenting on the delight of an extra hour and how the change in the chronological clock always affects their biological ones. I know nothing about this anymore. Whether it is part of my karma or not, in the dense urban environment where I happen to live; no matter the season, disregarding the height of my window, from where everyday there's a stubborn 'dude' with a yellow belly, blowing his throat loudly, in mornings' first light. There he goes: bem-te-vi, bem-te-vi. The wise feathered fellow knows I like to watch the sunrise.....

Les Figuiers de l'église des Carmes-Déchaussés, Arles

Pour continuer la série sur cette église d'une autre époque, voici quelques images des figuiers qui ont pris place dans le bâtiment - bel exemple de nature urbaine sauvage !

To continue the series on this abandoned French church, here are some images of fig trees that have taken place in the building - fine example of wild urban nature !

Baltimore Oriole, Icterus galbula and the Hummingbird Feeder

My Mom and Dad have a hummingbird feeder hanging just outside their kitchen window.

It is always a treat to watch the birds come to the feeder.

Yesterday Mom sent me this photo of a persistent Oriole who wanted the nectar also.  He stayed and drank for quite some time.

You never know what birds you will see int he city!

According to Wikipedia, the Baltimore Oriole is so named because of the resemblance or the bird's colors to Lord Baltimore.

Latin American Green Cities

Latin America's rural challenges
such as Amazonian deforestation, often receive a great amount of attention from the media, environmentalists and other observers around the world. However, the rapid rise in city populations of Latin America has had economic, political and social implications; and environmental considerations are a major part of this integrated puzzle.



- Latin America comprehends the most urbanized areas of the developing world.
- 81% of the population in Latin America live in cities.
- Traffic jam, land use policies, waste disposal and air quality are more immediate issues to the majority of the Latin American residents than the matters of rural areas.

Belo Horizonte Bogotá Brasília Buenos Aires

Curitiba Guadalajara Lima Medellin

Mexico City Monterrey Montevideo

Porto Alegre Puebla Quito

Rio de Janeiro Santiago São Paulo





Nine of the 17 cities assessed, derive more than 80% of their electrical energy from renewable sources (São Paulo 100%); policies on green spaces are widespread; Curitiba, the sustainability pioneer and the birthplace of "bus rapid transit" (BTR); São Paulo, harvesting methane to power the city and the state's climate change policies; Belo Horizonte, a leader in solar energy; Buenos Aires, setting targets for the public buildings; Rio de Janeiro, expanding cycle lanes and green corridors; Puebla, turning waste into cash; Porto Alegre, delivering "water the right way" are some of the highlights in the study.

The missing link: There is no clear relationship between overall environmental performance and the city income. For example: Curitiba, which ranked above average in the index overall, is within 15% of the income for three other cities with widely differing performances: Rio de Janeiro (above average) , Porto Alegre (average) and Guadalajara (below average). This contrasts sharply with the strong link between environmental performance and GDP per person found in similar EIU studies, including the European Green City Index and initial research taking place in Asia.

Still, according to the study, much has to be improved on transportation and urban sprawl issues. Experts predict that the infrastructure of most of these cities will come under increasing pressure from larger populations and the extreme weather effects of climate change; including floodings , droughts and storms. In addition, the growth of cities, outside of the formal planning framework will also continue. Adressing these challenges will require a broad, long term vision to balance urban redevelopment with restoring nature.

No matter how hard we try to behave in "sustainable terms" to avoid big loss, Nature seems determined to recover from what was taken from it; and the centuries relying on studies and on civilization did not provide regular citizens with the access to the science that would prevent them from having their lives reconducted by extreme events.



The Policeman and His Car

Shorty the Red Tailed hawk lives in a tree up high in our neighbor's backyard.

Shorty's mate has just given birth to a very loud and very hungry chick.

Chick stay's impatiently hungry all day and Shorty and his mate must chase down all the mice, snakes, squirrels and fish from the creek to feed the juvenile Buteo jamaicensis.

We drove up yesterday and Shorty was perched on my neighbor Steve's Police auto.

Adaptation is key to survival for wildlife in the Urban Core.

Les ruines de l'église des Carmes-Déchaussés, Arles

Les Carmes déchaussés ou Petits Carmes s'établissent en Arles en 1647. 
Sur un terrain acheté à l' extérieur de la ville, l' église est construite entre 1673 et 1678.  La voûte s' écroule en 1801. Au milieu du 19e siècle, le percement du canal de navigation d' Arles à Port-de-Bouc et la construction du quai modifient totalement ce secteur. 
Les bâtiments du couvent qui entourait l' église sont démolis. 
Seule une moitié de l' église, sans toiture, subsiste. Elle conserve encore une partie de son décor sculpté du 17e siècle (frise de rinceaux, têtes de profil, ...) .
Il ne subsiste aujourd’hui que sa façade dégradée, isolée par l’urbanisme moderne, en bordure de la voie rapide Marseille-Nîmes, à côté du Canal de Craponne.

Et depuis des années la nature y reprend doucement ses droits 

An abandoned church of Discalced Carmelites in Arles ... since years nature takes its rights gently
