Violet-capped Woodnymph / Beija-Flor-de-Fronte-Violeta

Thalurania glaucopis

Description:

(Gmelin, 1788)

Aves: Apodiformes: Trochili: Trochilidae: Trochilinae

Size/Tamanho: ~8cm - 11,1cm.

Weight/Peso: ♂ ~5,0g / ♀ ~4,0g.

Sex: ♂

Outro nome: Tesoura-de-Fronte-Violeta.

Habitat:

Their natural habitats are forests, especially humid ones, woodlands, weedy areas and fields. They have adapted to the anthropic environment, especially (but not limited to) rural backwater towns, and are often seen feeding in gardens.

Distribution: East & Southeast Brazil (Bahia to Rio Grande do Sul); East Paraguay and Northeast Argentina (Misiones); doubtfully North Uruguay.

____

Seus habitats naturais são florestas, principalmente as úmidas, áreas de mata e campos. Adaptaram-se ao ambiente antrópico, especialmente (mas não limitado a isto) cidades interioranas rurais, onde são comumente vistos alimentando-se em jardins.

Distribuição: Leste e Sudeste do Brasil (Bahia até o Rio Grande do Sul); Leste do Paraguai e Nordeste da Argentina (Misiones); duvidosamente no Norte do Uruguai.

Notes:

Thalurania glaucopis é um beija-flor da ordem Apodiformes, subordem Trochili, família Trochilidae e subfamília Trochilinae. O sujeito retratado é um macho.

Machos de Thalurania glaucopis possuem uma "coroa" violeta e são mais coloridos do que as fêmeas, que são mais pálidas. Não são pássaros estritamente nectívoros, e foram avistados caçando pequenos artrópodes em pleno vôo, como pequenos insetos e aranhas. Duas de suas flores favoritas são Malvaviscus arboreus penduliflorus e Malvaviscus penduliflorus, mas podem se alimentar de muitas espécies de flora. Não há subespécies registradas de Thalurania glaucopis.

Medem aproximadamente 11,1cm quando adultos e pesam cerca de 4,5g (este necessita confirmação). O bico costuma medir cerca de 1,8cm e a língua cerca de 4cm, ambos utilizados para que o beija-flor se alimente de flores em formato tubular. Durante o ritual de acasalamento, o macho voa ao redor da fêmea e exibe o peitoral colorido para impressioná-las. Habitam florestas, jardins e campos; isto também inclui cidades interioranas rurais. Quando em ambiente antrópico, não costumam ser agressivos, preferindo ignorar a presença humana mesmo quando se aproximam. Na natureza são conhecidos por serem o oposto. Dado a necessidade de contato constante com néctar, eles precisam de constante limpeza, que fazem quando chove.

Os machos não ficam por perto após acasalarem com as fêmeas; eles vão à procura de mais fêmeas para se reproduzir, estas que constroem o ninho e criam os filhotes. O ninho é em formato de tijela e é tecido com uma vasta quantidade de materiais. Geralmente, depositam cerca de um único ovo, que é incubado apenas pela fêmea. As fêmeas alimentam os filhotes com comida regurgitada, que inclui insetos, pois o néctar não é suficiente para manter a saúde dos filhotes. Os filhotes abandonam o ninho cerca de 20 dias após o nascimento. Os machos são extremamente territorialistas.

ENGLISH VERSION HERE:

Thalurania glaucopis is a hummingbird in the order Apodiformes, suborder Trochili, family Trochilidae and subfamily Trochilinae. The subject portrayed is a male.

Males of Thalurania glaucopis possess a violet cap are more colorful than the females, which are paler. They are not strictly nectarivorous birds, and have been sighted hunting small arthropods midflight such as small spiders and insects. Two of their favorite flowers are Malvaviscus arboreus penduliflorus and Malvaviscus penduliflorus, but are seen feeding in many species of flora. There are no subspecies of Thalurania glaucopis registered.

They measure approximately 11,1cm when adults and weight around 4,5g (this requires confirmation). The beak averages about 1,8cm and the tongue about 4cm, both of which are used for feeding on tubular-shaped flowers. During the mating ritual, the males fly around the female and display their brightly colored chest to impress them. They inhabit forests, gardens and weedy areas; this also includes rural backwater towns. When in an anthropic environment, they are not known to be aggressive at all, normally ignoring the presence of humans even when they get close. In the wild they are known to be the opposite. Due to the need of staying in contact with nectar, they need constant cleaning, which they do themselves when raining.

Males do not linger around after mating with the female, choosing to fly away and mate with as many as they can, and only the females build the nest and raise the offspring. The nest is cup-shaped and is woven with a vast amount of materials. Generally, they lay a single egg, which is incubated solely by the female. The females feed the offspring with regurgitated food, which includes insects as nectar is not enough to maintain them healthy. The offspring leave the nest after approximately 20 days. Males are extreme territorialists.

Well, I just looked at your content, and I'm simply amazed. You're blessed to live near all those species.

Perhaps not a Trochilid, but I bet you have plenty of exclusive fauna there that I crave to photograph. You crave my species, I crave yours. I'm soon gonna take a flight over to North America to photograph some foreign species and in like a year I'll program myself to shoot for Japan to photograph their species. We are never fully pleased by what we have haha. I'm sure you'll photograph some beautiful creatures over your region :)

Good one, Oscar - but doubt I would find any of Trochilidae species in my part of the world...

Thank you Zlatan Celebic. I encourage you to visit local parks in your city, especially those with plenty of wildlife. Try to ask friends and family or locals for information on preserved ecological areas; those are the places you will find most abundant bioforms. Weedy areas in backwater rural towns are usually abundant in wildlife. I'll be cheering for your success on this.

Beautiful one. Oscar, I'm jealous for not having a chance to see one of these beautiful creatures!
