Birds that have not reached NZ, but should

[Clinton9]

Birds that lives in forest/woodland and are not common birds, do not fly to NZ, for etc a Black-eared Miner that lives in restricted area of Australia and don't have way to fly to NZ.

Flying over 2,000 k/m from Australia, to NZ, is very expersive for birds, the fattest adult birds or fattest immature birds can fly to NZ.
Lean birds become extusted and dies in seawater, unless carried by cyclones.

Think of bar-tailed godwits.

[SomesBirder]

Once again, please answer why birds like the blue-billed duck cannot reach NZ.

[Clinton9]

Blue-billed duck had fast wing beats and would burnt its enygeries by time it be mid-sea between Australia and NZ.

Blue-billed duck rarely flies, the wings are smaller, but long, same wing shape as Ruddy duck.

They had never been in nz yet.

[SomesBirder]

I would like you to explain why the others cannot reach NZ either.

[boneywhitefoot]

I think at best one can only say its unlikely, after all the birds we have here had to come from somewhere didn't they?. Some have fast wing beats others have slow wing beats. NEVER say NEVER.

Birds Flight Foods Chance of come to Size
New Zealand

Australian Pelican Soaring, gliding, Fish Yes large
flapping less often
Slow wingbeats

Blue-billed duck Flapping all time water plants No meduim
when flying
Fast wingbeats

Magpie goose Flapping, with some water plants No large
gliding. Slow flier fruits
Very slow wingbeats

Black swan Flapping all time water plants,
when flying grasses Yes large


Pacific gull Gliding, with some fish, meat
flapping humen food Yes large-meduim

Silvereye Flapping & gliding fruits, insects Yes
(both) During autumn small

Rainbow lorikeet Flapping & gliding
Fast flier fruits, pollen Yes meduim-small

Fairy Martin both flapping & insects Yes small
gliding


You can understand why fish, insects, meats are more rich in enerygies than plants, and why black swan can fly to NZ while Magpie geese & Blue-billed ducks cannot fly to NZ.

EXPLAME: A two adult Pacific gulls and four adult Silver Gulls feasted on a 2 metres freshly dead Yellow-eyed Tuna fish washed on Goldcoast Beach, at Brisbane, Australia, while four black swans had a very lucky few days eating the grains meant for sheep and the farmer were away on holiday in USA. Lots of grains available to black swans that had to walk for 10 yards, from lake, to paddock.
Sheep were wary of swans & stayed away from swans. Whilemean 20 Australian pelicans were herding the 1,000 fish toward shore and feasting on fish, with gulls. 15 adults and 5 1-year-old pelicans. Excess foods are becoming bodyfats, and all birds above became fat with 3 days...4 fat black swans, 20 fat pelicans, 6 fat gulls.
Three Magpie geese and one Blue-billed ducks feeding on natural foods-just water plants or water weeds, and have limited bodyfats.
Magpie geese had long board wings and a slow flier, with very slow wingbeats, while Blue-billed duck had fast wingbeats, but rarely flies. Magpie geese grazing & up ending for foods while Blue-billed ducks diving for foods.
3 days later the storm come, with strong winds, the Blue-billed duck feel the strong wind and deaided to fly away...it running+ flying across the water, because strong winds make flying easier. These magpie geese saw a adult Wedge-tailed eagle in distance and took off from water and flying...flapping, but strong gale caught the 3 magpie geese and a Blue-billed duck in midair and carries the 4 birds to Goldcoast, Brisbane.
A 1-year-old Wedge-tailed eagle arrived in distance, approaching fast eastward, the 6 gulls and 20 pelicans become frightened and took off, they flapping then glide. Then the pelicans & gulls get caught in strong gale that is carrying magpie geese & duck.
A feral dog arrived at sheep paddock, along with strong wind, then dog chasing the poor sheep. Black swans swimming in lake, the lake is 20 yards, not large & water is 60cm deep, so swan took off...running+flapping, then the 4 black swans flying fast & eastward, get caught by strong gale. Powered by high temperature and sun the wind became a strong cyclone. 1 Blue-billed duck, 2 Pacific gulls, 3 magpie geese, 4 Silver gulls and 20 pelicans tried to fly strong back to land, they tries hard, with their excellant flying skills, but cyclone getting slightly stronger, kept blowing these birds across Tasman sea.
Then midsea, 1,000k/m from Australia, the 6 gulls, 20 pelicans, became little tired and can see just sea, and have long glidings and less flapping flight, they learn to gliding more often, when they see fish on surface of sea, they dropped to eat the fish and have a rest before they carry on flying. They had burnt half of their bodyfats. 4 Black swans find themselves in midsea, then lower their flapping speed and are flapping more slowly, with few glidings. 3 Magpie geese carry on flying slowly, with slowier wingbeats.
A Blue-billed duck flying fast, with fast wingbeats, but burning bodyfats faster then black swans.
At 1,500k/m the 20 pelicans and 6 gulls still flying with long glidings and fewer flappings, with less bodyfats. Black swans flapping slowly, their feet slightly hanging from underside tailcoverts, they learning to glide, with little bodyfats.
Magpie geese flying even more slowly, but with no bodyfats, they become extusted and land in seawater, while a fast-flying Blue-billed duck find itseft becoming extusted and feel tired, then land in seawater, ran out of bodyfat and it did not seen the land.
Approaching NZ land, 20 pelicans, with 6 gulls see the land (NZ) and increase the number of flapping with less gliding, then land in sea near shore. so Pelicans-15 adults and 5 1-year old, are tired and sleeping in beach, while 2 Pacific gulls are sleeping some distance from pelicans. Four Silver gulls are sleeping on grassy areas on little isle raise from seawater.
Four black swans notice the land, then they carry on flapping slowly, then once reached the shore, they land on sea near shore and go to sleep on beach, with one male swan popping his eyes to check for predator.
Three magpie geese were extusted and on sea, sleeping...one male Great White shark noticed the goose when it flapping its wings, and swim to have a look...gave the goose a nightmare...then shark realised the geese were good to eat, ...a male hammerhead shark approach the geese, but Great White shark chased the hammerhead shark away. The magpie geese got a fright when shark grabbed a goose. Two geese tried to fly, but they are too extusted and fall asleep. Then Great White shark grabbed three magpie geese, by one, by one and ate the geese. The last magpie goose managed to fly for 20 yards, but shark followed the goose and grubbed it. Extusted Blue-billed duck is asleep, then its heart stopped beating and duck dies. Another hammerhead shark-adult female ate the freshly dead Blue-billed duck.
Outcome: The two Pacific gulls, after waken from sleeping in late afternoon, took off and in flight they look for food, found a freshly dead Blue penguin and tore it into skin & bones, a female Pacific gull found a freshly dead yellow-eyed mullet fish nearly and ate it, swallow the fish in one gulp. The four Silver gulls waken and flew looking for food and found people and their New Zealand relative-Red-billed gulls...they tried to get the food, ate fewer chips & bread pieces and insects, and noticed the Red-billed gulls.
Both gulls stayed alive and breed, but their chicks, when adults, hybrid with Kelp gulls and Red-billed gulls.
The four black swans waken and noticed two humen in distance, then they took off and flew...they saw the coastal lake and flew to lake...land in water...they noticed waterweeds and some eel grasses in water, and grasses at edge of lake. then they ate the plants, so in evening they feel well fed and roost in middle of lake. They have bright future in NZ, able to breed and have lot of natural foods to eat. The 20 pelicans waken in late afternoon and went fishing in shore they had landed, found lot of young yellow-eyed mulet fish in seawater, and they fed well, and after touring the NZ, they breed on next year later, produce 40 chicks. Their future are bright.
But the three magpie geese and one Blue-billed duck are dead and now the new teeth for a Great White shark and a Hammerhead shark.

Bar-tailed godwits feeding on worms at mudflats in Firth of Thames, during Feb-March before they migrate to China. When they left NZ on March they had very thick bodyfats, to last them for max 8 days of flying to China. When they arrive at Mirada beach, NZ on September they were thin with no bodyfats. On March the godwits flies fast, but on Sept they avoid flying unless they are frightened.

Sorry about the words got mixed as this website had mixed these words, it was about birds, with foods, flight, sizes, chance of come to NZ.

Pelican: flapping, gliding, soaring, slow wingbeats, flapping less often and food-fish, and able to come to NZ and large size

Blue-billed duck:flapping all time when flying, fast wingbeats and food: waterplants, and cannot come to NZ and meduim size.

Our bar-tailed godwits are good explames, they helped us understand about their migration, bodyfats, flight, foods, age, distances between their breeding homes and NZ.

[SomesBirder]

I cannot understand you, and your 'explames' do not make any sense.

[Clinton9]

Ask the members for help as there are some members that are knowleglable about birds and of help to you.

[SomesBirder]

I need you to explain why all of those other birds that you marked in the list cannot reach New Zealand. I think that you are purposely trying to annoy me now.
