Saving our Shared Birds: a Trinational Vision (2010)
• This is the first complete and
comprehensive conservation
assessment of landbird in North America.
• Highlights the importance of the links
and of trinational collaboration in North
America

Promoted by Partners in Flight• As a collaborative effort of many authors and
institutions from USA, Canada and Mexico

The Power of Linking People through migrating, and so, shared birds
Selasphorus rufus
To preserve this bird we HAVE
to work together, to ensure the
presence of BOTH breeding and
wintering habitats

What do we need to preserve them?
• Information: basic natural history and ecological information about breeding foraging, distribution, population status and
ecological trends.
• Comunicating and sharing: develop a strategy to make information available to researchers, students, educators and sciticents.
![Page 11: The Mexican Perspective on Hummingbird …• 57 species in North America • 57 species in México • 15‐17 USA • 5 Canada • 30% of the Mexican Hummingbirds Migrate: breed](https://reader034.fdocuments.in/reader034/viewer/2022052612/5f0a99e67e708231d42c6f02/html5/thumbnails/11.jpg)
Research
• Monitoring permanent sites: demography and trends
• As hummingbirds eat nectar they get dusted with pollen, collecting pollen while monitoring
can tell us a lot about phenology of the interaction and help to document changes dur
to climate change.

Investigating what hummingbirds need to
survive, successfully reproduce, and
maintain thriving populations

The mission of the WHP is to work together to maintain thriving hummingbird
populations and their habitats for present and future generations.

The value of partnerships
• Information generated through research along the network can help to:
a)Understand population trends
b)Relate abundances and phenology of birds and plants used
c)
Model possible results for populations living under fragmentation habitats or climate
change for example

All this information…
• Is needed to better propose conservation measures that promote hummingbird
conservation,
• Working as a country can not ensure bird conservation and so
• Working together is the a better solution that can make us stronger when spreading the
word of the need to protect pollinators.
